Thank you Banded for posting your experience.
I used SuPrep and didn't find it bad at all. The only thing I worried about is that if I drink/eat too much, especially in a short time, I will puke it up(side effect of my diabetic med), but I didn't have that issue at all. I too was completely unaware of anything until after the procedure and my wife stated getting me up and dressed afterwards was like waking the dead.
