peeps...no need to feel embarrassed or ashamed! There were several professionals in the rehab I went to and we also have many here on this forum who are in recovery as well!
That is why I think talking to your prescribing DR (or even an Addictionologist) is a good idea. He/ she can help guide you to find a way to safely detox off the Oxy and possibly suggest several non-narcotic meds you could try once you are well. (Alot of times OTC meds work once we get clean and our perspectives change!)
If you don't want to go inpatient rehab there are several meds they can give you to safely detox at home such as Clonodine which worked very well for me both in rehab and upon discharge.
