I have been taking Oxycodone 10/325 for over 6 years, and my doc just changed my medicine to Oxycontin (20mg) after seeing my most recent MRI. I just finished my Oxycodone medicine this morning, and am due for my next dose (if I still had them). I am supposed to start the new medicine but am nervous because of the things I have heard/read. Does anyone know if I am going to feel "drugged" if I take one after taking my regular medicine? Should I suffer until morning? Any help is appreciated. Advise?
