I have been on subutex since I first successfully got clean. I've been in consistent recovery since August 15th, 2015. I have made attempts before with withdrawing from heroin and did so cold turkey with little success before I got on subutex. It was down right miserable. The drugs I have used were before 2015. Thats was heroin Percocet and cocaine but only a few times. I basically got introduced to heroin at 18 then started injecting it within a few weeks of starting it. My addiction progressed to doing between 4-10 bags a day. I may have used a few years but it ruined my life.
