Don't worry about the scope, nst. It can even be FUN (ha)! If you buy a billion magazines, have several hot baths, limit your food intake two days before, and drink Lemon Gatorade diluted with water - you'll be good to go. You'll be out for the scope. Won't remember a thing about it. And maybe they'll have an answer for you when you wake up.
When are you having the lovely procedure done?
