pain
"I started out on Darvocet many years ago for my knee pain and ended up on Percocets.  That was a horrible place to be after years of use and it would take so many more than prescribed to work.  Since I started taking methadone I haven't felt this good in the last 25 years of dealing with this pain and pain medicine.  I take what I am prescribed and even though I still am a bit uncomfortable my quality of life is so much better!"
