You don't need to wait a month for the methadone to be gone. You go about three good days with no methadone or any other opiate including percs or whatever and I can induct you relatively painlessly. As long as you score a 26 on the COWS sheet that is foolproof I guarantee. Let me know when you're ready. You'll have to go into w/d anyway before induction. I would get it over with and begin. God bless.
