I have been taking 7.5 milligrams, 2 each, of percocent for about a month, prior to that it was lortab, the lowest dose, first 2 did it, then 3, then up to 4 at one time, then I took one percocet plus 4 lortab now I've been taking 2 of the percocet. i want to stop. how is the best way. I have access to 10 m of valium. If take that can i come off cold turkey or do I still have to wean off
