Yes it possible to build up a tolerance for
percocets because thst what you was taking. People bodies differ and react different depending what you put in it. More then likly you would have mild withdraals. But 4 percocets a day is like taking 20 mg of
oxycontin. I would be worried if it was that short period of time. You might feel irratiable or unable to get a good night sleep. A lot of people think you can only get hooked if you abuse prescription meds
