"i have an infected tooth with a dead nerve that needed a root canal. i got half the root canal done and need to wait for the infection to clear up. i&#039;m taking major antibiotics but it&#039;s still taking a while and i&#039;m in a lot of pain. the percocet has helped immensely. i waited too long to take it last night and had to take a trip to the er for morphine! the morphine was not much different than the percocet. my problem was that i waited. i have been taking one every 6 hours which is says on the bottle but i think i need to do it every 5 hours. hopefully that&#039;s ok to do. i&#039;m also on 800 mg of ibuprofen every 6 hours. i have not experienced any nausea but yes,i guess i am constipated but i have only been eating soup any way."
