Gabapentin for Anxiety: Benefits, Side Effects, and Dosage Guide

You've probably tried multiple anxiety medications. Maybe an SSRI that made you feel flat. A benzodiazepine your doctor didn't want to refill. Now someone mentioned gabapentin—and you're wondering if it's worth trying.

Here's what I've learned treating patients like you: Gabapentin can work remarkably well for specific anxiety presentations, but it's not FDA-approved for anxiety, the evidence is mixed, and more importantly—why are we discussing it before ruling out the medical causes of your symptoms?

A significant subset of patients labeled "treatment-resistant" aren't resistant at all. They have undiagnosed iron deficiency, suboptimal thyroid function, vitamin D deficiency, or chronic inflammation driving their anxiety symptoms.

Let me explain what gabapentin actually does, when it works, when it doesn't, and what should be investigated first.

Quick Summary: Gabapentin for Anxiety

Before we dive deep, here's what you need to know:

• FDA Status: Not approved for anxiety (off-label use)
• Evidence: POSITIVE for social anxiety; NEGATIVE for panic disorder; LIMITED for GAD

• Response Rate: 32% (social anxiety) vs 14% placebo
• Starting Dose: 100-300 mg at bedtime
• Therapeutic Range: 900-2,400 mg/day (divided TID)
• Time to Effect: 2-4 weeks for full benefit
• Common Side Effects: Dizziness (20-30%), somnolence (15-25%), ataxia (10-15%)
• Major Risks: Respiratory depression with opioids, physical dependence, abuse potential (15-22% in at-risk populations)
• Best For: Social anxiety, chronic pain + anxiety, alcohol recovery, patients who can't tolerate SSRIs
• Avoid If: History of substance abuse, severe kidney impairment, concurrent opioid use, elderly at fall risk

Bottom line: Gabapentin is a useful tool for specific anxiety presentations, but it's not first-line treatment, carries real risks, and won't work if underlying medical factors are driving your symptoms.

How Gabapentin Actually Works (It's Not What the Name Suggests)

Despite the name "gaba-pentin," gabapentin does NOT work on GABA receptors.

Here's the actual mechanism:

Gabapentin binds to α2δ-1 calcium channel subunits in the central nervous system. This:

• Reduces excessive glutamate release
• Dampens neuronal hyperexcitability
• Decreases the brain's tendency to amplify harmless signals into anxiety

Think of it as a "noise gate"—the kind used in audio production. When your brain is over-amplifying normal sensory input (a crowded room becomes overwhelming, a work presentation triggers panic), gabapentin turns down that amplification.

This is fundamentally different from:

• Benzodiazepines (Xanax, Ativan) → Enhance GABA-A receptor activity, work immediately, highly addictive
• SSRIs (Lexapro, Zoloft) → Block serotonin reuptake, take 4-8 weeks, work systemically
• Buspirone → Partial 5-HT1A agonist, builds up over weeks

Gabapentin sits somewhere between: slower onset than benzos (2-4 weeks), faster than SSRIs (weeks not months), different mechanism than both.

The Clinical Evidence: What the Research Actually Shows

Social Anxiety Disorder: POSITIVE Evidence

Pande et al. (1999) published the landmark trial in Journal of Clinical Psychopharmacology:

• Study design: Randomized, double-blind, placebo-controlled
• Participants: 69 patients with social anxiety disorder

• Dosing: Gabapentin titrated to target dose (900-3,600 mg/day)
• Results: 32% response rate (gabapentin) vs 14% response rate (placebo)
• Statistical significance: p = 0.04

Clinical interpretation: Gabapentin works for social anxiety. The effect is modest but real. One in three patients benefit significantly.

This is the strongest evidence we have for gabapentin in anxiety.

Panic Disorder: NEGATIVE Evidence

Pande et al. (2000) tested gabapentin in panic disorder:

• Result: No significant difference from placebo
• Conclusion: Gabapentin is not effective for panic disorder

Why the difference? Social anxiety involves anticipatory anxiety and situational hyperarousal. Panic disorder involves acute, paroxysmal surges of anxiety. Gabapentin's mechanism may dampen the former but not prevent the latter.

Generalized Anxiety Disorder (GAD): LIMITED Evidence

The evidence for GAD is weak:

• No high-quality RCTs comparing gabapentin to placebo
• Small open-label studies suggest benefit
• Pregabalin (Lyrica, structurally similar) has better GAD evidence and is FDA-approved for GAD in Europe

Clinical takeaway: If you have GAD and need a gabapentinoid, pregabalin has stronger evidence. But SSRIs or buspirone remain first-line.

Side Effects: What to Actually Expect

These percentages come from FDA prescribing information and clinical trials:

Common Side Effects (Dose-Dependent)

Dizziness: 20-30%

• Usually worst in first 2-4 weeks
• Improves with slower titration
• Take at bedtime if bothersome

Somnolence (Sleepiness): 15-25%

• Can be therapeutic if anxiety disrupts sleep
• Problematic if it impairs daytime function
• Dose timing matters (bedtime vs divided)

Ataxia/Unsteadiness: 10-15%

• Risk increases in elderly
• Fall risk in those with balance issues
• Start low, titrate slow

Fatigue: 10-15%

• Often co-occurs with somnolence
• May improve after 4-6 weeks
• Consider dose reduction if persistent

Peripheral Edema (Swelling): 5-10%

• Ankles and feet primarily
• Not dangerous, but uncomfortable
• Dose-dependent, reversible

Weight Gain: 5-10%

• Average 2-3 kg over 6-12 months
• Less than mirtazapine or atypical antipsychotics
• Mechanism unclear (not increased appetite in most)

Cognitive Slowing: Variable

• Subjective "brain fog" in some patients
• Worse with higher doses (>2,400 mg/day)
• May improve with extended use

Serious Side Effects and Safety Concerns

2019 FDA Warning: Respiratory Depression

The FDA issued a drug safety communication warning that gabapentin increases risk of serious breathing problems when combined with:

• Opioids (morphine, oxycodone, hydrocodone)
• CNS depressants (benzodiazepines, alcohol)
• Pre-existing respiratory disease (COPD, sleep apnea)

Clinical relevance: If you take any opioid regularly, gabapentin carries significant risk. This is a critical conversation with your prescriber.

Physical Dependence and Withdrawal

Gabapentin causes physical dependence with regular use:

• Abrupt discontinuation can trigger withdrawal symptoms
• Withdrawal syndrome includes anxiety rebound, insomnia, tremor, sweating, and in severe cases, seizures
• Always taper gradually (typically 10-25% per week)

Abuse Potential

Despite being unscheduled until recently, gabapentin has recognized abuse potential:

• 15-22% misuse rate in populations using opioids
• Taken at high doses (>3,000 mg) for euphoric effects
• Often combined with other substances

If you have a history of substance use disorder, gabapentin should be used cautiously or avoided entirely.

Renal Clearance

Gabapentin is 100% eliminated by the kidneys:

• No liver metabolism (safe in liver disease)
• Requires dose adjustment in kidney impairment
• Can accumulate to toxic levels if renal function declines

If your creatinine clearance is <60 mL/min, your dose must be adjusted.

What Your Doctor Should Check First

Here's what most providers miss.

Before we discuss gabapentin dosing, these medical conditions must be ruled out. Research shows they frequently cause or worsen anxiety symptoms:

Thyroid Disorders

Hyperthyroidism can perfectly mimic panic disorder and generalized anxiety:

• Tachycardia (racing heart)
• Tremor
• Sweating
• Anxiety and restlessness
• Heat intolerance
• Weight loss despite normal appetite

Critical test: TSH with reflex Free T4/T3

If your TSH is <0.5 mIU/L and you have anxiety symptoms, you may have hyperthyroidism—not primary anxiety disorder. Gabapentin won't fix this.

Subclinical hypothyroidism (TSH >2.5-3.0 with normal Free T4) also causes anxiety, particularly when combined with depression. Optimizing thyroid function to TSH 1.0-2.0 often eliminates anxiety without psychiatric medication.

Iron Deficiency

Ferritin <75 ng/mL is associated with:

• Chronic anxiety and inner restlessness
• Fatigue worsening anxiety symptoms
• Restless legs disrupting sleep (worsening anxiety)
• Poor concentration (perceived as anxiety)

2025 research update: Males with ferritin deficiency show dramatically higher depression and anxiety risk (OR = 14.13). Iron deficiency in women causes restless legs syndrome, which disrupts sleep and worsens daytime anxiety.

Standard reference range for ferritin is 15-200 ng/mL, but anxiety symptoms often don't resolve until ferritin is >75-100 ng/mL.

Vitamin D Deficiency

Vitamin D <30 ng/mL is linked to:

• Generalized anxiety disorder
• Social anxiety symptoms
• Panic disorder
• Seasonal worsening of anxiety
• Treatment-resistant anxiety (especially if CRP >3 mg/L indicating inflammation)

Meta-analysis from 2025: Vitamin D supplementation significantly reduces anxiety scores (SMD = -0.28, p <0.05), with strongest effects in patients with baseline deficiency.

Optimal target: 40-60 ng/mL (not the standard "sufficient" level of >20).

Vitamin B12 Deficiency

B12 <400 pg/mL causes neuropsychiatric symptoms years before anemia develops:

• Anxiety and panic symptoms
• Cognitive dysfunction ("brain fog")
• Memory impairment perceived as anxiety
• Irritability and mood instability
• Psychotic symptoms in severe cases

Critical: The standard "normal" range is >200 pg/mL, but psychiatric symptoms commonly occur between 200-400 pg/mL.

2025 research: 84% of patients with B12 deficiency reported marked symptomatic improvement with replacement therapy. Anxiety symptoms improved alongside cognitive function.

If your B12 is 200-400 pg/mL, check MMA (methylmalonic acid) and homocysteine to confirm functional deficiency.

Magnesium Deficiency

2025 comprehensive review confirms magnesium is effective for anxiety:

• Dose: 400-500 mg daily (glycinate, threonate, or taurate forms)
• Timeline: Works within 2 weeks (as fast as gabapentin)
• Mechanism: Modulates NMDA receptors, reduces glutamate excitotoxicity, regulates HPA axis
• Safety: Excellent (GI upset is main side effect)

Symptoms of magnesium deficiency:

• Anxiety and inner tension
• Muscle tension and restlessness
• Insomnia
• Irritability
• Migraine headaches
• Palpitations

Serum magnesium is a poor marker (only 1% of body magnesium is in serum). Clinical diagnosis is based on symptoms + response to supplementation.

Before gabapentin, try therapeutic magnesium for 4-6 weeks. Many patients find it eliminates the need for prescription medication.

The Comprehensive Lab Panel I Order

When a patient presents with anxiety, I order:

Tier 1 (Everyone):

• TSH with reflex Free T4 and Free T3
• CBC with differential
• Comprehensive Metabolic Panel (kidney, liver, glucose, electrolytes)
• Vitamin B12
• Vitamin D (25-OH)
• HbA1c (rule out diabetes/prediabetes)

Tier 2 (Based on Clinical Suspicion):

• Ferritin, serum iron, TIBC (if fatigue or restless legs)
• Free T3, Anti-TPO antibodies (if TSH borderline)
• MMA, homocysteine (if B12 200-400)
• RBC Magnesium (if available; serum magnesium if not)
• CRP (if treatment-resistant or chronic medical illness)
• Morning cortisol (if suspect adrenal dysfunction)

Why this matters: In my practice, I find undiagnosed medical causes in approximately 40% of patients labeled "treatment-resistant." Once we correct the underlying deficiency, many no longer need gabapentin—or if they do, it finally works effectively.

Gabapentin Dosing: The Practical Guide

Starting Dose

Week 1: 100-300 mg at bedtime

• Start low to assess tolerability
• Bedtime dosing minimizes daytime sedation
• Most patients tolerate 300 mg without issue

Titration Schedule

Week 2: 300 mg twice daily (morning + bedtime)

• Total: 600 mg/day
• Assess for dizziness, sedation

Week 3: 300 mg three times daily

• Total: 900 mg/day
• This is the minimum therapeutic dose for anxiety

Week 4+: Adjust based on response

• If 900 mg helps but not enough: Increase to 1,200 mg (400 mg TID)
• If 1,200 mg helps but not enough: Increase to 1,800 mg (600 mg TID)
• Maximum for anxiety: 2,400 mg/day (800 mg TID)

Typical Therapeutic Range

Most patients respond between 900-1,800 mg/day divided TID

Higher doses (2,400-3,600 mg) are sometimes used but:

• Benefit plateaus around 1,800 mg for anxiety
• Side effects increase substantially
• Higher doses are for neuropathic pain, not typically needed for anxiety

Timing Matters

Gabapentin has a short half-life (5-7 hours), so dosing schedule affects efficacy:

• Once daily (bedtime): May work for nighttime anxiety, but daytime coverage is minimal
• Twice daily: Provides better coverage but still gaps
• Three times daily (TID): Optimal for stable blood levels and consistent anxiety control

Clinical pearl: If gabapentin "works great for a few hours then stops," you likely need TID dosing, not a higher dose.

Time to Onset

Week 1-2: Some patients notice reduced anxiety, especially physical symptoms (muscle tension, restlessness)

Week 2-4: Full anxiolytic effect emerges

Week 4-8: Continued improvement as dosing optimized

Unlike benzodiazepines (work in 30 minutes), gabapentin requires consistent dosing for 2-4 weeks to see full benefit.

When Gabapentin Is the Right Choice

Based on the evidence and my clinical experience, gabapentin works best in these scenarios:

1. Social Anxiety Disorder (Strongest Evidence)

Gabapentin often works well when you have:

• Fear of social situations, public speaking, performance anxiety
• Physical symptoms prominent (tremor, sweating, racing heart)
• SSRIs tried and failed or not tolerated
• Need something that works faster than SSRIs but isn't a benzodiazepine

Why gabapentin works: Dampens the hyperarousal response to social situations. Takes the "volume" down on anticipatory anxiety.

2. Chronic Pain + Anxiety Overlap

This approach fits when you have:

• Neuropathic pain (diabetes, post-herpetic neuralgia, radiculopathy)
• Anxiety symptoms worsened by pain
• Need medication that addresses both

Why gabapentin works: FDA-approved for neuropathic pain. If anxiety co-occurs, you treat both conditions with one medication.

3. Alcohol Recovery (Reduces Cravings and Anxiety)

This approach fits when you have:

• Early alcohol recovery (first 6-12 months)
• Anxiety that historically triggered drinking
• Need something non-addictive and safe

Why gabapentin works: Reduces alcohol cravings, dampens withdrawal-related anxiety, doesn't have abuse potential like benzodiazepines in recovery populations.

Evidence: Multiple RCTs show gabapentin reduces heavy drinking days and improves abstinence rates.

4. "Wired and Tired" Presentations

This approach fits when you experience:

• Physically exhausted but mentally anxious
• Can't "turn off" brain at night
• Poor sleep despite being tired all day
• Anxiety feels physical (jittery, tense, restless)

Why gabapentin works: Addresses physical anxiety symptoms, promotes sleep without hangover effect, doesn't worsen fatigue like SSRIs can initially.

5. When SSRIs Aren't Working

Gabapentin may help when you've experienced:

• Previous SSRI trial caused intolerable sexual dysfunction
• Severe GI side effects from multiple SSRIs
• Activation/agitation from SSRIs worsened anxiety
• Need alternative mechanism

Why gabapentin works: Completely different mechanism (calcium channels, not serotonin), different side effect profile, no sexual dysfunction.

6. When Avoiding Benzodiazepines Is Important

Gabapentin may be preferable when you have:

• History of substance use disorder (benzodiazepines are contraindicated)
• Occupation requiring alertness (pilot, surgeon, driver)
• Elderly patients at fall risk from benzodiazepines
• Preference for non-controlled substance

Why gabapentin works: Not a benzodiazepine, less cognitive impairment, not scheduled in most states (though this is changing).

Clinical Considerations Requiring Discussion

Certain situations require additional evaluation before starting gabapentin. These aren't automatic disqualifiers—they're factors we'll discuss during your assessment:

Substance Use History

Gabapentin has recognized abuse potential (15-22% misuse rate in certain populations). If you have a history of prescription medication challenges or substance use disorder, we'll discuss:

• Whether gabapentin is appropriate for your situation
• Alternative anxiety treatments with lower misuse risk
• Monitoring protocols if gabapentin is the best option

Recovery doesn't disqualify you from treatment—it changes how we approach it.

Kidney Function

Gabapentin is 100% eliminated by the kidneys. If you have kidney disease or reduced kidney function:

• Doses need adjustment based on your kidney function tests
• Standard doses may be too high
• We'll work with your kidney doctor if needed

We'll check your kidney function before prescribing and adjust accordingly.

Current Opioid Medications

The FDA issued a 2019 warning about respiratory depression when combining gabapentin with opioids (morphine, oxycodone, hydrocodone, tramadol).

If you currently take opioid medications, we'll discuss:

• Whether gabapentin is safe in your situation
• Alternative anxiety treatments
• Monitoring protocols if combination is necessary

This doesn't mean you can't get treatment—it means we need to choose carefully.

Fall Risk Concerns

Dizziness and unsteadiness occur in 20-30% of patients. If you're over 65 or have balance concerns:

• We'll start with lower doses and titrate more slowly
• We'll discuss fall prevention strategies
• Alternative medications may be more appropriate

Your safety is the priority—we'll find an approach that works.

Panic Disorder

Clinical trials (Pande et al., 2000) showed gabapentin wasn't effective for panic attacks specifically. If panic is your primary concern:

• SSRIs have stronger evidence for panic disorder
• Gabapentin may still help with co-occurring generalized anxiety
• We'll discuss which approach targets your specific symptoms best

Not every medication works for every type of anxiety—we'll match treatment to your presentation.

What Relief Actually Feels Like: Gabapentin vs Benzodiazepines

Patients often ask: "How is gabapentin different from Xanax?"

Benzodiazepines (Xanax, Ativan, Klonopin): Like slamming on the brakes

• Work in 30-60 minutes
• Acute suppression of anxiety
• Euphoric or "high" feeling in some
• Physical relaxation and sedation
• Highly addictive
• Tolerance develops (need more over time)

Gabapentin: Like turning down the volume knob

• Works over 2-4 weeks
• Gradual reduction in baseline anxiety
• No euphoria (in therapeutic doses)
• Reduced physical tension without heavy sedation
• Less addictive (but still has dependence/abuse potential)
• Stable effect without tolerance in most

The feeling: Most patients describe gabapentin as "taking the edge off"—situations that used to trigger intense anxiety become manageable. The physical symptoms (racing heart, sweating, tremor) are less intense. The mental rumination is quieter.

It's not a "high." It's a return to baseline.

Alternatives to Consider

If gabapentin isn't right for you, consider:

SSRIs (First-Line for Most Anxiety Disorders)

• Escitalopram (Lexapro): Best evidence for GAD
• Sertraline (Zoloft): FDA-approved for panic, PTSD, social anxiety, OCD
• Takes 4-8 weeks but highly effective
• Well-studied, safe, guideline-recommended

Buspirone (BuSpar)

• Non-benzodiazepine anxiolytic
• No dependence, no abuse potential
• Takes 4-6 weeks to work
• Good for generalized anxiety, less effective for panic

Pregabalin (Lyrica)

• Structurally similar to gabapentin
• FDA-approved for GAD in Europe (not US)
• More consistent absorption, more potent
• Scheduled (controlled substance), more expensive

Hydroxyzine (Vistaril, Atarax)

• Antihistamine with anxiolytic properties
• Works acutely (30-60 minutes)
• Non-addictive
• Sedating, anticholinergic side effects

Beta-Blockers (Propranolol)

• Blocks physical symptoms of anxiety (tremor, racing heart, sweating)
• Excellent for performance anxiety, social situations
• Taken PRN (as-needed)
• No CNS effects, no dependence

Cognitive Behavioral Therapy (CBT)

• Gold standard non-medication treatment
• As effective as medication for GAD, social anxiety, panic
• No side effects
• Lasting benefit after treatment ends

Clinical recommendation: Combine medication (if needed) with CBT for best outcomes.

The Diagnostic Approach: When Neither Gabapentin Nor SSRIs Work

If you've tried multiple medications—SSRIs, buspirone, gabapentin—without sustained benefit, here's my systematic investigation:

Step 1: Verify Medication Trials Were Adequate

• Dose: Were you at therapeutic dose? (Gabapentin 900-1,800 mg/day, SSRI at target dose)
• Duration: Did you give it 8-12 weeks?
• Adherence: Did you take it consistently as prescribed?

Many "treatment failures" are actually inadequate trials.

Step 2: Rule Out Medical Causes

Complete lab panel as outlined above. Address any deficiencies found:

• Vitamin D <30: Supplement 5,000 IU daily, recheck in 8-12 weeks
• B12 <400: Methylcobalamin 1,000 mcg daily
• Ferritin <75: Iron bisglycinate 25-50 mg daily
• TSH >2.5: Consider thyroid optimization (levothyroxine trial)
• Magnesium deficiency: Magnesium glycinate 400-500 mg daily

Timeline: Give nutritional interventions 8-12 weeks before declaring failure. Ferritin takes 3-6 months to fully replete.

Important: You don't have to wait months in suffering while we optimize labs. We often start gabapentin or other anxiety treatment while simultaneously addressing nutritional deficiencies. Both tracks run in parallel—and treatment often works better once underlying issues are corrected.

Step 3: Reassess Diagnosis

Is this really primary anxiety disorder? Or could it be:

• ADHD (often presents as anxiety, restlessness, "can't shut off brain")
• Bipolar disorder (anxiety between mood episodes, antidepressants/gabapentin may worsen)
• PTSD (requires trauma-focused therapy, medication alone rarely sufficient)
• Medical anxiety (hyperthyroidism, cardiac arrhythmia, pheochromocytoma)
• Substance-induced (caffeine overuse, alcohol withdrawal, stimulant medications)

Step 4: Consider Augmentation or Combination

Rather than switching to a fourth medication, augmentation often works:

• Gabapentin + SSRI: Synergistic effect, may work when either alone fails
• L-methylfolate (7.5-15 mg): Enhances medication response, especially if folate <15 ng/mL
• N-acetylcysteine (1,200-2,400 mg): Modulates glutamate, helps anxiety and OCD
• Low-dose quetiapine (25-100 mg): For severe anxiety with sleep disturbance

Step 5: Therapeutic Intervention

Medication alone is rarely sufficient for sustained anxiety relief:

• Cognitive Behavioral Therapy (CBT): First-line, evidence-based
• Exposure therapy: Particularly for social anxiety, panic, PTSD
• Mindfulness-based stress reduction (MBSR): Reduces baseline anxiety, prevents relapse
• Somatic therapy: Addresses physical manifestations of anxiety

The Bottom Line

Gabapentin works for specific anxiety presentations—social anxiety disorder, chronic pain with anxiety overlap, alcohol recovery, and patients who can't tolerate SSRIs.

But here's what matters more: Gabapentin is not FDA-approved for anxiety, the evidence is mixed, and it won't work if underlying medical conditions are driving your symptoms.

Before trying gabapentin, before increasing your SSRI again, investigate the root cause.

Anxiety symptoms are often the final chapter of an untold medical narrative.

Your ferritin is 45 ng/mL—technically adequate, but anxiety symptoms rarely resolve until it's >75.

Your vitamin D is 28 ng/mL—"sufficient" by standard criteria, but anxiety improves significantly when optimized to 50-60.

Your thyroid is "normal" (TSH 3.2), but optimizing to 1.0-2.0 might eliminate anxiety without any psychiatric medication.

Your magnesium is low-normal, but therapeutic supplementation (500 mg glycinate) works within 2 weeks—as fast as gabapentin, without the risks.

This is diagnostic psychiatry: investigate first, medicate second, optimize always.

A Patient Story

Sarah, 34, had tried three SSRIs and was considering gabapentin when she came to my practice. Her previous providers had focused only on her anxiety—but her lab work told a different story: ferritin of 28 ng/mL and vitamin D of 19 ng/mL.

Within 8 weeks of targeted supplementation, her anxiety scores dropped by 60%. She never needed gabapentin. "I spent two years thinking I was broken," she told me. "Turns out I just needed someone to actually investigate."

This is what comprehensive evaluation looks like.

Ready for a Comprehensive Evaluation?

If you've tried multiple medications without sustained improvement, it's time for a thorough medical investigation.

What to expect:

1. 75-90 minute initial assessment — We'll review your full history, not a rushed 15-minute med check

2. Comprehensive lab workup — Testing for medical causes most providers miss

3. Systematic treatment plan — Addressing root causes, not just symptoms

4. Monthly follow-ups initially → Transition to quarterly once stable (typically 3-6 months)

Investment: Initial evaluation and follow-ups covered by most insurance plans (cash rates: $350-450 initial, $150-200 follow-ups; sliding scale available for uninsured). Lab work typically $20 copay with insurance. Most patients achieve stability within 3-6 months and transition to maintenance visits 2-4 times per year.

Most patients see significant improvement within 2-3 months when we identify and treat underlying deficiencies—often without needing gabapentin or multiple psychiatric medications.
