How Long Meth Treatment For Oxy?

I have a friend in Meth treatment for Oxy--

I do not really know anything about the treatment and would appreciate someone telling me how long it goes on? How does he get off of the Meth?
I did know someone that was on Meth for years-- I suspect that she didn't want to get off of it, but ... .

He said that he would just go to bed for a few days and get off of it. I feel that the doses would be reduced gradually ... But even then, how long are you in treatment before you "get off" the Meth. I just do not know and can not respond with any intelligence. I just do not know what to say.

I am supporting his decision, and am glad that he made the decision. Also in the past 2 months since he started treatment I have been paying for it. He will shortly have funds, but I am there for him 'till he gets them as this is one of the most important things he will ever do with his life. It has put me in a bind, I will eventually recover, but it will be worth it for him to get his life back.

Any information would be greatly appreciated.

Thank you in advance!

You're more likely to get an answer if you post this question in the Pain Pills forum. Good luck!
plz if possible get him to change to subutex its a lot easier to detox off in the long term and how long it takes is totally dependent on him and how big a dose he is on generally you reduse at 2.5-5mg a fortnight then when you reach 20-25mg you change to subutex <your dose will be btween 6-10mg of subutex >you then reduce at around 1-2mg a fortnight until 2mg then at 0.4mg a week this is only what i did it took me 30mths to get from 120mg of methadone to clean.........
