Recovery & aftercare

Why you can't sleep in early recovery and when it gets better

It is 3 AM and you have been lying in bed for four hours. You used to pass out from substances. Now you can't sleep at all. Your brain literally forgot how to fall asleep naturally.

Why

Substances don't give sleep. They give unconsciousness. You've been bypassing natural sleep mechanisms for years. Now those mechanisms have to relearn.

Timeline

Alcohol: peaks weeks 1-2, improves weeks 3-6, normalizes months 2-4. Opioids: peaks week 1, improves weeks 2-6. Benzos: weeks to months (slowest). Cannabis: peaks weeks 1-3, improves weeks 4-6.

What helps

Sleep hygiene. Exercise (not near bedtime). Low-dose melatonin (0.5-1mg, not 10mg). Magnesium glycinate. CBT-I (most effective long-term). Avoid Ambien, nightly Benadryl, and caffeine after noon.
