Methadone for the last 14 months I'm on 305 mg that is the dose amount it took to get to before I wasn't having any more withdrawals from the herion/ fentanyl. But now I have been stuck on this medicine and had tried to quit a few times or take my dose to a lower level and then I am unable to function or do what I need to as a father husband and boss. I want to be clean so bad.
