bowel preparation
"Cannot emphasize this enough, I am a hypochondriac and love to worry so naturally I only focused on the less than favorable reviews. 
Well let me tell you, don't worry. Tastes a LOT like BC powder chased by a cherry coke. Yucky but over quick and at least to me no where near as bad as some described. Actually the worst part was drinking so much water. Made me burp a bunch and feel bloated somewhat. Since I was hungry from only drinking liquids this was not completely unwelcome. 
Felt chilled for a little bit but I think this was more from being so nervous. 
Took an hour to kick in and since then has been doing its job. No cramping, just lots of "I gotta go".  If this is the worst then this will be about the easiest procedure ever."
