bowel preparation
"This is my second colonoscopy.  The first one 3 years ago my doctor had me do an over the counter Miralax-Dulcolax bowel prep the day before the procedure.  It was a several hour ordeal and not very fun between the extended time on the toilet, the amount of water I had to drink and the ahem chafing down there from wiping.  This time around my doctor prescribed Suprep.  This has been a much easier experience.  First of all, I'm pretty much cleaned out after a couple of hours, unlike the several hours from my first go around.  That by itself is worth it since I've had to endure fewer wipes and hence less chafing. The taste isn't so bad.  I drink Pedialyte from post drinking hangovers and I would say that Suprep tastes exactly like Pedialyte."
