Hi Maria~~
Well, anything is possible, but I don't think it is a realistic expectation. Certainly, the oxycodone can be stopped, but doing so abruptly is going to send the body and brain into a tailspin and in all honesty, I do not see being out of withdrawal in the timeframe of ten days. To come off such a high dose in such a short period of time, I would suggest rehab where monitoring and aftercare can be provided to you.
Whatever your decision, I am wishing you well. Oxycodone was what I tapered from... 50-60 mgs a day. We can find our lives again after using it. Keep the hope alive.
All best wishes
