I was just switched to Opana 40mg ER 2x daily. I was on Oxycontin ER 20mg 4 x daily. I wish I had NEVER changed. It is horrible. For ME, It doesn't work nearly as well as the oxy did. I regret making the change. It has been one week now and I am still trying to get my Dr. to switch me back. He wants to try MS Contin, but I have heard that it is even worse than Opana! I tried MS Contin a few years ago with my previous Dr. and had to stop taking it because it just made me feel irritated all of the time. Very grumpy and sleepy. Not a "euphoric" sleepy, but a "exhausted" sleepy. But, I know everyone is different. This is just my experience. Some people really like Opana. Another thing I am still wondering about is...Did I experience some sort of withdrawal when I switched over? Because the first 4-5 days I took the Opana, I felt like I had the flu- I had headaches , body aches, nausea, just an over all feeling of feeling sick. But, I suppose it could have been the Opana OR that I was really just sick? In my opinion, I wouldn't switch any meds before a vacation, no matter what it was. Good Luck-Best wishes with your situation!View Thread
