When I had my wisdom teeth out, they numbed my mouth up, and filled me with nitrous. I felt heavy like a brick but it felt good. All four of mine were very impacted and I was put on some pretty powerful painkillers afterward. Not much swelling though, just took a three hour nap and it wore off... I know what you mean about the garbage can though, I could have made a moat of blood around my house.:sleep_125
