I detoxed on temgesics before, but relapsed several months later.

One thing that I got out of that experience is that (for me), less is more. I'm tapering now from oxy. When I get down to a crossover dose amount (20mg oxy), I'll switch to norco/hydro, after I get down to 10mg of hydro I'll switch over to buph, but not nalaxone, it will be straight temgesic .2mg and I will only take 2 tabs in am and 1 in evening.
I refuse to take mega doses of anything. I built myself too large of an addiction to buph my last detox because of using so much of it.

There is a difference between detox and maintenance. That's where I went wrong.
