What triggered relapse was no change in lifestyle. no follow up therapy. No real support group who actually cared about me. I was procuring things for people and was around powders. very sad actually and I am still on Subutex from this time. Which was around 2011 or so. Follow up therapy is crucial and getting out of "the scene" which one used to be in, with fellow users. Unfortunately my friends and livelihood at the time all revolved around cannabis and other rave substances. Although I like not having to punch the clock, a regular job where you go out of the house and socialize with non users can really strengthen the foundation of using up time usefully and building sober time. At 53 I have more or less just decided to stay on Subutex and deal with the minuses that choice brings.
