I hate prep, too. In the past, I have used golytely, which is just awful. I couldn't keep it down. But most recently, I used the Miralax & Gatorade prep. Miralax is an over the counter powder laxative. You mix an entire bottle into a 64 oz. Gatorade (lemon-lime is best, obviously, you can't use a red flavor), and you can't taste a thing. You just taste the Gatorade! It goes down so easy. But, it sure does work. However, it has made me (and a few others on the forum) a bit dehydrated. But I'd take it any day over any other prep in a heartbeat.
