Opioid tolerant? Been on pain meds for 7 years nd seems like my percocet isnt helping anymore unless I take larger amounts.

Yes. You are addicted to, and habituated to percocet. The longer you take it, the more you will need to get the desired effect. You will also suffer some side effects if you stop abruptly. You should see a pain management specialist to help control you pain without narcotics.
