Colonoscopy ... piece of cake. All my naysayer friends told me horror stories of the procedure but more importantly, the prep (clean-out). Nothing to it! I used Prepopik for the cleanse and the taste wasn't bad. (Far better than the stuff I used 10 or 12 years ago.) Everyone was pleasant. The facility was spotless. Dr. Filippo was vey pleasant, as was his staff. If you're afraid of a colonoscopy, don't be. If your friends tell you "horror" stories, they obviously didn't go here or they're just trying to scare you and sound like a martyr.
