First let me say you have nothing to be ashamed of...have you lived a good life? Did
methadone offer you a chance to break the addictive cycle you'd been living and live life the way you wanted to live? Then whats to be ashamed of? You wouldn't be ashamed of having to take any other medication for this long would you?
So that sort of leads me to my next question--and I think it really has a lot to do with YOUR question of "Do I stand a chance?"
What are your reasons for getting off methadone right now and switching to subs? I am gonna guess it's either because your tired of the clinic or because your on a lower dose and you figure WHY NOT?
I just really think the reason why people switch has a lot to do with wether someone does well on subs or not....when people switch for the wrong reasons it sets them up for a big disappointment. If your switching to lessen your ties to the clinic or because of some of methadone's side effects I would say you've got great chances....but if your doing well on methadone and really don't mind it BUT don't like the idea of being on "the 'done" and THAT's the reason your switching you may be in for a big surprise because if methadone is working well for you it doesn't mean subs will be the same....it doesn't mean it won't-but you get the idea.
Either way your switch should be really easy since your on such a low dose anyway....but just because the switch is easy doesn't mean it will be the right medication for you. The GOOD news is, if things don't work out going from subs to methadone is very easy-just take your next dose-so you have nothing to lose by trying. It's the switch your making now that's the hardest.! I have no idea why your docs making you wait so long between doses, but hey, he's the doc not me!
One thing I would suggest? Try to make sure you have an easy "in" back to the clinic if things don't work out with the subs....and try to remember a life well lived--on medication or off--is never ANYTHING to be ashamed of.
