Health - Nootropics to repair/normalize brain function from 13 years of drug use

[oggy]

Swim has detoxed from methadone use 8 weeks ago and can still feel that brain fog. It seems as tho its been getting worse over the last few weeks as his mind has been racing with negatives. He finds it hard to concentrate on one thing, like reading anything bigger than one paragraph. He's also had a mild headache and feeling a bit sick for the last few weeks and developed a slight cold or hay fever?.

He's changed his diet, working out, taking multi vits, epa fish oils, etc. Caffeine works for about an hour so its only really good for pre workout.

Could Swim have developed hay fever? But how can one just develop an allergy? Are allergies not just a negative thought? If the brains powerful enough to make one ill with negative emotions then one could then develop an allergy to the summer and blame it on pollen. Science would prove me wrong tho, it always knows best, even tho science proves itself wrong all the time. Sorry thinking out loud here.

Whats the best nootropics that repair neurotransmitters from serious drug abuse or clear that foggy head?
