I have been taking 15mg immediate release oxycodone, 10 tabs per day for neck pain for about 5 years. I have been taking as the doctor prescribes and no more. It seems like lately I have been feeling like I am going through withdrawls even though I have not stopped taking the medication yet. The detox clinic I am going to does not use methadone or suboxone and for that I am grateful, as I don't want to have to go through more withdrawls later. I don't know what to expect, they say they are going to give me barbituates and anti-anxiety meds and anit-nausea medicine to help with withdrawls. Is it going to be hell? can anybody ease my mind that I am going to be alright. I am so scared but I don't want to take pain meds anymore. I am not taking to get high, just started to take them for a neck injury and then kept having to take more and more overtime because I built up a tolerance. Any response would be greatly appreciated.
