Timely subject as I'm just now finished with my first liter of the 4 liter Golytely prep. I was told to throw away the flavor packets and use Crystal Light instead. Also to refrigerate. I did both and the stuff is still barely tolerable. Plus, 4 liters in a short time is a LOT of liquid.

That said I put a colonoscopy in the same category as a PSA test and some others for that matter. People will be arguing about their value forever. Each will have valid points from their point of view. But all that doesn't matter to me. I want all the information I can get so I can make the best decsions about the most important machine I own, my body.

Without information all the arguments are pointless.
