ive taken subs for over 3 yrs now, i take 16 mgs a day and i cant seem to cut back anymore .Dependency runs deep in my fam. after reading some forums i am thinking about going to methadone becouse they havent done any longterm research on suboxone , the highest they have scienifically studied i can find is 3mgs a day, at least with methadone they have long term research, can any one tell me a little more about the subz, another thing i dont like about the subz is how long it supposedly stays in your system due to how long you take it!!! Any suggestions will be greatly appreciated
