I was unable to stop oxy without going on suboxone replacement therapy for a time, although I did try to taper on my own. I'm not saying you would have to have suboxone, there are people who can go without and get clean, but if cold-turkey and tapering don't get you there, it may be something to consider. Let me know if you think about doing a suboxone program. There is a lot to consider there.
