Shotspine,

I can't really give you a CLEAR answer to that. But I am the same way. I do much better on Hydrocodone than the other. When I took Percocet before, I would get very nauseated. Hydrocodone does not do that to me and probably because it has more Tylenol in it which does not uspet the stomach. So, ONE Vicodin a day usually does the trick for me. Maybe someone will come along that has more experience with both.
