I was on methadone about 10 years. I made a decision to slowly detox. I had to instruct my clinic as to how much and when to reduce the dose. The clinic is a profit making business, they would rather you were a long time customer. I would reduce dose by 5 mg, then stay on that dose for a month or more. You allow your body to adapt to the lower dose. At one time, I had been on as much as 120mg a day. On my schedule, I was able to get off methadone with little or no withdrawals. It may have taken a year, but was best thing I ever did. If I can do it, anyone can. You need to get to the place where the high no longer matters, the money you've been spending is too much and you know you must change. Its the fear of sobriety that stops too many.
