I had this done last year too. I tell ya though, that crap they made me drink was HORRIBLE. The nurse told me to get the orange flavored drink, that most people like the orange flavored one. Well, that was total B.S. I was down to my last 12-16 ounces when I puked it all into the kitchen sink. 30 minutes later I was standing in the shower with my boxers and shorts on because, without warning and I do mean without warning, the flood gates opened and nothing but mud came out. We're talking the consistency of coffee.
They really know how to break a man down. Making him crap himself like that . Horrible, just horrible. And to make it worse, it was in front of my wife and kid.
