Withdrawal timeline phase by phase
Below is the typical withdrawal timeline for ice (methamphetamine). Individual experience varies — duration of use, average daily dose, polysubstance use, age, liver/kidney function, and co-occurring mental health all shift the pattern. The phases below describe the average presentation in clinical settings.
Phase 1 · Crash phase (1–3 days)
Acute crash
- Extreme exhaustion
- Hypersomnia (sleeping 16+ hours)
- Increased appetite
- Severe low mood
- Inability to feel pleasure
Phase 2 · Days 4–10
Acute withdrawal
- Intense cravings
- Severe depression
- Anxiety
- Irritability
- Disturbed sleep
- Psychomotor slowing
- Suicidal thoughts in some cases
Phase 3 · Weeks 2–4
Subacute withdrawal
- Mood gradually improving
- Sleep slowly normalising
- Cravings continue but less acute
- Anhedonia improving
Phase 4 · Months 2–6
Post-acute withdrawal
- Cognitive function recovers slowly (memory, concentration, executive function)
- Cravings triggered by people, places, situations
- Sleep architecture continues to improve through 6 months
Medications and medical management
No specific anti-craving medication for methamphetamine withdrawal. Symptomatic treatment: short-term benzodiazepines for severe agitation, low-dose antipsychotics (e.g. olanzapine) for psychotic features, antidepressants for ongoing depression beyond 4–6 weeks.
Where to detox safely
Inpatient or supervised setting strongly preferred for first 7–14 days due to suicide risk and craving intensity. Many people genuinely cannot function in their normal environment during early withdrawal — residential settings remove access to substance, manage sleep and nutrition, and provide direct mental health monitoring.

What helps in the post-acute phase
The hardest part of ice (methamphetamine) withdrawal is rarely the first few days — it is the weeks that follow. Sleep is disrupted, mood is low, cravings come and go in waves, and cognitive sharpness recovers slowly. The interventions that consistently help: structured psychological therapy (CBT, motivational interviewing, mindfulness-based relapse prevention), peer support (SMART Recovery, AA, NA, CA — choose by fit), continued GP and addiction-medicine follow-up, ongoing relapse-prevention medication where relevant, and a written relapse-prevention plan that names triggers and rehearsed responses.
People who engage with structured aftercare for 12 months or more after a withdrawal episode have dramatically better long-term outcomes than people who treat withdrawal as a one-off event. The single most predictive question to ask any program: "What does aftercare look like in the 12 months after I leave?"
Frequently asked questions
How long does ice (methamphetamine) withdrawal last?
Acute ice (methamphetamine) withdrawal typically lasts 2–6. Post-acute symptoms — sleep, mood, cravings — can persist for weeks to months. The acute phase is the medically dangerous one; the post-acute phase is uncomfortable but rarely dangerous.
Is ice (methamphetamine) withdrawal dangerous?
Ice (Methamphetamine) withdrawal is not directly life-threatening but is uncomfortable and produces high relapse risk if unmanaged. Methamphetamine withdrawal is rarely directly life-threatening but it produces severe depression and high suicide risk in the first 1–2 weeks. Acute methamphetamine-induced psychosis IS a medical emergency.
Can I detox from ice (methamphetamine) at home?
Not safely without medical supervision. Inpatient or supervised setting strongly preferred for first 7–14 days due to suicide risk and craving intensity. Many people genuinely cannot function in their normal environment during early withdrawal — residential settings remove access to substance, manage sleep and nutrition, and provide direct mental health monitoring.
What medications help with ice (methamphetamine) withdrawal?
No specific anti-craving medication for methamphetamine withdrawal. Symptomatic treatment: short-term benzodiazepines for severe agitation, low-dose antipsychotics (e.g. olanzapine) for psychotic features, antidepressants for ongoing depression beyond 4–6 weeks.
