Why do I keep hearing the prep is worse than the test? What does the prep involve?
A 24-hour fast and a, er, cleanout by magnesium citrate. You will be VERY familiar with the inside of your bathroom. Liquid-only diet and no colored liquids (red or purple) because they can resemble blood on camera. No alcohol (hey, Doc, beer is a clear liquid, right? No?) For my first one I made the mistake of using regular toilet paper and ended up feeling like I'd been sitting on a belt sander. For the second one, medicated wipes. Sooo much better!
Whatever it is, it's apparently worse than full-blown Ebola.
Extreme EVACUATION of the intestine by drinking a gallon of stuff that “encourages” it.
