Actually, after re-reading these posts and thinking about my experiences since getting prescribed the morphine, I do know that my energy level overall has decreased. My pain has been relieved for a longer period of time, but I am not sure I want to make that trade-off. OP, just like you said, when I don't take morphine, I can re-dose my oxy's, like you do your hydrocodone, and get a burst of energy and better mood, even if I re-dose every hour. Since taking the morphine, I thought it was a tolerance issue, but I bet the morphine is hanging out in the receptors, blocking the oxy's full effect. I guess I need to get rid of the morphine, but for some reason, I still like to take it at night, even though it ruins my first oxy of the morning. Once again, sorry Kaldius, but I have been thinking about all this and your posts have helped me formulate my thoughts and words.
