Suprep Bowel Prep Kit
"Let me first agree with all the comments that it doesn't taste good. But it is much better for me than my previous experience with Golitely which did not. Be sure to chill everything thoroughly before starting...I used a very long drink straw and put it to the upper rear of my mouth so it mostly went past my tongue and it isn't too bad that way with a Gatorade green apple chaser.  I had much less cramping and appears to have done the intended job well. Just be near the toilet and tell your family to not get in the way."
