Methadone I’ve tried 3 seperate times and unsuccessful because I would start using on top of it everytime. Suboxone got me off of pain pills years ago but hasn’t been successful for me since I’ve been on heroin/fentanyl. I always go to the doctor once then never go back because I try to make the switch over to suboxone but each time I get sick and quit it always puts me in withdrawal and never really helps much.
