I've used Methadone, and am currently using Morphine. The Methodone wasn't very effective for my pain. The morphine helps a lot more, but it does tend to make me drowsy at higher doses. For breakthrough pain I use Dilaudid. I used to take Percocet for a year and a half, but became concerned about all the acetamenophine intake I was getting from it.

Good luck at finding whatever works best for you!!!
