It's not so bad... if you have a general anaestetic you don't even remember dropping off to sleep. They make you count down from 10, and according to my girlfriend, I didn't even make it to 6. When you wake up from sugery is the worst part tbh. Dry mouth, fuzzy vision, weird smell, it's all very confusing. Then of course you're asked if you want food or something to drink, to which you reply;
"What is there that doesn't taste like sick?"
and you're told things like toast or sandwiches. Why the hell would I want toast at 11pm? I'll tell you why, because their cassarole tastes disgusting.
