How to Recover from an Amphetamine Comedown: Top 10 Questions on Sleep, Food & Supplements
1. Why does an amphetamine comedown cause depression and exhaustion?
Amphetamine empties the presynaptic reserves of dopamine and norepinephrine. When the drug wears off, your brain experiences temporary neurotransmitter depletion, causing anhedonia (inability to feel joy), mental fatigue, and low motivation.
2. How long does a speed crash last?
- Acute Crash: 6 to 18 hours after the last dose.
- Hangover Phase: 24 to 48 hours of mental sluggishness.
- Full Recovery: 3 to 5 days with proper rest and nutrition.
3. What supplements help speed up recovery?
- L-Tyrosine (500–1000 mg): The direct amino acid precursor needed to manufacture fresh dopamine.
- Magnesium Glycinate (200–400 mg): Relaxes jaw muscles, stops bruxism, and calms physical tension.
- Vitamin C (1000–2000 mg): Powerful antioxidant; acidifies urine to accelerate renal elimination of amphetamine.
- Melatonin (1–3 mg): Promotes natural sleep onset without dangerous drug interactions.
4. What should you eat with zero appetite?
Focus on liquid and soft calorie-dense foods: protein smoothies (with banana and peanut butter), warm bone broth or miso soup, scrambled eggs (rich in tyrosine and choline), and fresh juicy fruits (melons, berries).
Frequently Asked Questions
Why does an amphetamine comedown cause depression and exhaustion? ▾
Amphetamine depletes your brain's stored dopamine and norepinephrine. Once the drug clears, temporary neurotransmitter deficiency causes low mood, fatigue, and anhedonia until fresh dopamine is synthesized.
What supplements help restore dopamine and stop muscle clenching? ▾
L-Tyrosine (500-1000 mg) provides the direct building block to rebuild dopamine. Magnesium Glycinate (200-400 mg) relaxes tight muscles and stops jaw clenching.
How can you fall asleep after taking speed? ▾
Drink Vitamin C (1000 mg) or orange juice to acidify urine and accelerate amphetamine excretion, take Magnesium Glycinate with Melatonin (1-3 mg), and avoid smartphone screens.
