Opana is oxymorphone and is quite similar to morphine....you can dump this, especially with some help through detox - wont be fun or easy - but is doable....good luck
Although I have no knowledge of your doc I sure would like to congratulate you on your decision for detox and taking your life back.. When you get out come back and educate us on Opana also I'm sure you would be an asset for others who are addicted too it.. I wish you well and again great decision.. lesa
