I Am A Addict. I Stopped Using Iving Heroin A

I am a addict. I stopped using Iving heroin a year and a half ago. I was 6 months clean then relapsed on subutex. Stop using subs a month ago yesterday I went to a MD and she gave me a vivtrol shot cause I'm Craving subs and I wasnt ready to give up subutex cause it's the only thing that works for me. Even tho I was never prescribed I got them from a friend who's my best friend we did H together drop acid did alot of drugs together. Anyways Here I am a day into vivtrol and really wish I would have gotten a REAL subutex prescription and have a MD dose me correctly.
