Most likely you'd be better off taking a med like lyrica or another drug that deals with nerve pain on top of the percocet. Opiates don't usually kill nerve pain alone.

I gave up all my meds for a six month time period and I felt much better. It was enough time for my body to get rid of all the built up medication and for me to be able to start fresh again.

For my legs Zanaflex seems to work well, but it does cause drowsiness so it must be taken at home and when you don't need to drive.

I've heard that Cymbalta can also help quite a bit, but I'm afraid to get on that regularly becuase of the side effects.

Good luck!
