I agree, the prep is the worst. I had a colonoscopy and endoscopy (getting from both ends!) last year, and they (thankfully) put me out for it! So, the worst was the liquid cleansing...the stuff tasted horrible, and I lived in the potty!! I hope yours goes well, and I'm keeping my fingers crossed that the results show nothing wrong! by the way, DH had one earlier this year, and they clipped out a few polyps, which was good. Could've turned into cancer if he didn't get it done! So, perhaps if anything they will be able to do some preventative maintenance!! 8)
