I am a long time opiate user, went to treatment centers, detoxes, done it on my own.
haha I am also very experienced with opana, used to get the yellow hexagon 40 mgs I believe?
But coming off of that was worse than coming off of any other opiate i've done, including heroin (snorted/smoked/iv), oxycontin, etc. Just wait it out. The first week is terrible but I really don't recommend the use of suboxone or other drugs that try to ween your tolerance down. I usually tend to have a harder and more unpleasant time coming off of those. Good luck and get off that shit, it's nasty
