Are you going to a doctor or a clinic to get the methadone and are you taking the methadone to try and quit the oxys?How long have you been taking the methadone? Please be well informed about what you're getting yourself into with the methadone..Gather as much info as possible from this site...I learned first hand you can't always believe what the doctors and clinics tell you about it.I was on methadone for over a year.I went cold turkey off of 25 mgs 9 months ago.
