Acetaminophen / oxycodone
"Percocet is great for relieving my chronic pain. I have endometriosis, and have tried so many pain relievers- Naproxen,  Tramadol, Norco, and MS Contin to name a few. Oxyxodone has worked best for me because the onset is fast and it is a little stronger than Norco and Tramadol. The only downside is I only get about 3 hrs of pain relief from one dose, but its a life saver when your in horrible pain."
