my husband used heroine for about 4 months and when he tried to get off of it he was gettin bad withdrawals so we decided to go with methadone. He used methadone for 10 days (30 milligrams) and then decided to quit cold turkey from it! He has not had bad withdraws just body aches and sleeping a lot, a lot. Is this normal? I thought he would suffer from no sleep (insomnia)! Is it cause he was not a long time user???
