The prep was completely miserable. They are going to have to really work to convince me to go through that again. I'd had a colonoscopy before, but they used a different kind of prep that didn't require drinking so much of that solution. It still wasn't pleasant, but I didn't feel completely traumatized like I did this time. I also had trouble when I woke up being in really bad pain from gas. Again, I didn't have that problem the first time. Better you than me.
