"this medicine works great! i&#039;m only 20 years old, have torn my acl in my right knee 2 times, and had to have rods and pins put in my knee cap when i was 16, since then i&#039;ve had 3 surgeries on it and when i turned 18, my doctor told me about oxycodone. since i&#039;ve been 18, and now 20, i&#039;ve been taking percocet, at first i was on 15mg 3 times a day, just recently he bumped me up to 30mg 3 times a day. the pain nearly goes away for 2 hours at a time. my doctor told me they would work for 6-8 hours at a time, that is not true and if i don&#039;t take them for a day i experience withdrawals. i feel guilty for taking them because i am so young, and everybody gives me a hard time for it, but the pain is not tolerable without them. it&#039;s true it really works!"
