Once you get to the hospital, your brain will go on auto pilot. At least mine did. I do recall one funny incident -- I was in the pre-op/recovery area, with my wife there, and there was one doctor wandering kind of aimlessly around, with a very far-off and vacant look in his eyes. Finally, he comes over to my bed and asks "Are you Mr. Little? I'm your anesthesiologist." I'm thinking, "Oh no, you're not!" It turned out that my surgeon had changed the schedule around, and he was having to adjust on the fly.

You are in good hands, and time will go more quickly that you can imagine, especially if they put you on good painkillers! ;-) Good luck -- our thoughts are with you!
