I was on suboxone for a year straight with a couple of slips of using heroin (smoked) back in 2014. I had been using heroin for 8 months prior to getting on suboxone. when i got to a low dose and went through a break up, i stopped the suboxone and went back to using heroin.  then i went back on suboxone another year later and it turned into using suboxone and using heroin intermitently. fastforwarding to today, years later, I have been prescribed suboxone which I have been attempting to start but have been having a hard time giving myself enough to to start the induction process because my cravings have been so intense. Today, my drug of choice is fentanyl (smoked).
