Yeah, I have. It doesn't hurt much, from what I remember. I was really little, like six or something. I had been sick all year, and the docter took out my Tonsils and Adnoids... The tonsils hurt, but the adnoids didn't as much as the tonsils...I am not sure how exactly he got them out... I forgot... But shortly afterwards, I cought pnemounia (sp??) and that was bad. But out of all of it, the adnoids were the easiest part... It should take 30 min to an hour for everything. You shouldn't have to stay in overnight, unless you have a bad reaction to something. I was allergic to the seditive, but that is like a 1/100 case. Tell me how you do after it all! and G'luck!
