I've very interested in this as I have only had a GA 3 times in my life, but all 3 times have experienced terrible terrible naseua afterwards. (Last time, as soon as I woke up I said "I'm going to be sick" and took off the oxygen mask, only to have the post op nurse shove it back on, hold it there and say "of course you aren't going to be sick, you've had the strongest anti-nausea medication". I was sick. On her and in my mask!).

Anyway FS didn't give me a choice last time, but I would be interested to hear from others that have chosen not to have a GA, as I'd much prefer not to!
