On a daily basis, I take 2x 10/325 vicodin. I had surgery Thursday and was given 5/325 Percocet. They told me to alternate the Percocet and Vicodin every 4 hours. I wasn't even going to bother taking the Percocet, but my pain is kicking my ass. What can I expect differently from the Percocet? Any help would be great.
