Sure that's fine. There's a suboxone/methadone forum here also. There's quite a few posters who have taken subs for opiate addictions.
I'm not sure if your physician would be able to prescribe off label. Most doctors that I know of that prescribe are psychiatrists and are only allowed to have a certain number of patients receiving treatment at a time. It is a pretty closely watched system so I have my doubts that a family MD would have clearance to prescribe.
