I just had my first, they removed a benign polyp..
The prep wasn't as bad as the horror stories I had heard. I was proscribed Prepopik for the cleanse, Its a powder you mix with water, the chug it down, and drink a few extra cup of water... to prevent dehydration... from the "evacuations"
You take this prep twice, last dose 6 hours before the procedure?
I saved the mixing glass that came with the kit to serve beer tocertain of my friends when they are over....
It took over a week for me to return to my normal bowel movement activity though...
The worst part for my was being hungry..... I do not do well on an empty stomach.... but that is a serious first world problem
