I have been taking 4 7.5/500 percocet from my dentist. At first I took 4 of them and they gave me a nice buzz and killed the pain. Now I take 5 percs and only seemed to get "high" or what I call high for about 2 hours. Next question being... If I wanted to have a bit more would it be worth it to eat another pill or to snort a pill. Never tried snorting one, but I know it kicks in faster and might not be as much of a waste because of the speed it hits you.
