Pill instead of Liquid

I just read an ad in Prevention magazine for a pill that is now available for colonoscopy prep. Anyone who has had to drink the awful liquid as prep will be interested. From what I read, you need to take between 12 and 20 of these pills, depending on your doctor's instructions, but you get to choose your own 64 oz. of clear liquid to drink with it. Imagine drinking tea, apple juice, and or 7-Up instead of that nasty, salty stuff!
