Normal
The procedure is nothing compared to the prep. You basically starve for three days, then have to drink a lot of nasty stuff, even AFTER you have graphic evidence of what the heck it is going to do to you. The next day you are woozy from dehydration and lack of sleep, because even AFTER the main drama is over, there are little "episodes" all night. By the time you get to the doctor's office, you are delighted to have the procedure, because it means that you are soon going to be able to go home, have something to eat and drink, and take a nap.
