Yes, percocettes are very powerful, and very addictive. If they didn't help your pain, I doubt that taking more of them will. It makes no sense to take a larger dose, because they are dangerous. I don't think your resistance to alcohol, can affect the way the percocettes work on you. They are two completely different things, and one has nothing to do with the other. Sure hope you feel better soon. Be careful with the percs. They are hard to get off of once your addicted. It's no fun.
