I have been taking norco 10/325 for the past five years up to three times a day if necessary along with Tramadol 2 pills up to 4 times a day. This combination worked very well. Now my pain management doctor wants to switch me to opana ER and opana. I don't know why we have to fix what is not broken. She claims that opana doesn't give you the "euphoric" feeling that apparently Norco does. I have never gotten a euphoric feeling from Norco, just wonderful pain relieve. Does anyone know about this?
