Don't worry mate, I've been under for major stuff 3 times, the worst part is that your stomach doesn't "wake up" right away so you have to be REALLY careful what you eat afterwards. (or you'll see it again very soon).
The last time I was in, my nurse didn't have a clue what was going on, gave me a full hot meal as soon as I woke up. After they cleaned up (me, the room, etc) the regular nurse had a fit. I think she may have strangled the other one 'coz I never saw her again, hmmm?
On the brighter side, you'll get to eat ice cream and Jello
PS: My last time was two neurosurgeons for 5 hours, fusing my neck. Damn that Z3 and the rough ride.
