I have been taking Opana (oxymorphone) for 4 years, and am detoxing from it for so long that I feel like I am losing my mind from it. I would love to know how long it will take to get my old brain back. I am fearful a good bit of the time now. I mean extremely fearful throughout my life. I have no desire to travel or go into any unknown situation. I am wondering how long, and if I can indeed, be healed. Thanks Marie
