I dont believe methadone has anything to do with weight gain or loss, its your life style that changes , your eating habits your activity level. Ive been off of methadone for over a year and ive lost 40 plus pounds , but was due to the change of lifestyle, i exercise and eat healthy . When i was on it i didnt care what i looked like so i didnt follow a strict regiment.
Ive been off Methadone 6 weeks today. Ive put on 15 lbs since jan... when i started tapering down... evidently everyone is different.
