I can relate to the lack of sleep. It will come. Just hang in there and no matter what don't use. Your body and mind will get back to a place where you won't need to "take" anything to function, sleep, breathe, etc. It's not an overnight process. Our brains have been re-wired by the opiates. It takes time to heal.
Aminos help, Protein, vitamins, and lots of water. At 4 months clean from a 60-80 mgs per day hydro habit, I can say that my sleep is just about back to normal.
