Do i have to much of a tolerance for pain medicine?

i find that when im prescribed any sort of pain pills i have to take like triple the dosage for it to have any effect sometimes even four times. is there anything i can do to not take that many i know it can be harmful to my liver. i think i built up the tolerance when i was on percocet 10/325 for almost 5 months and i went from taking 1 every four hours to taking 3 every 3 or four hours but again is there anything i can do to lower this tolerance?
