I was just released out of a detox center that i was in for a week to try to get off methadone. IF YOU GET VERY SICK IT CAN BE FATAL!! So be SURE to get proper help. MY doc. told me it could take up to 2-3 months to get the withdrawls to go away. I don't sleep for days at a time , even on sleep meds. IT SUCKS!! The worse thing I've ever had to experience. Subutex has helped my withdrawls a lot but you have to be super careful not to create any more addictions with that one two. It's not just a mental addictions. Your body goes crazy without it. GOOD LUCK!!!
