I know this is an ancient post but can't the clinic tell you how to taper down, and aren't they the one's who are responsible to do that? Three years is a long time to be on methadone when the goal is to get off of say heroin or something isn't it? I guess I don't get the actual purpose and goal of clinics?
go down 5-7mg per week.
once you hit 10-15mg go down 2.5-5mg per week
good luch
