bowel preparation
"Before trying MoviPrep, I initially bought a different laxative that came in a 4L antifreeze-looking bottle.  Once I got home and looked at the bottle I was terrified at having to drink 4 liters of the stuff.  After further research I found moviprep and was relieved that it was only half that volume.  I expected it to taste much worse.  It was fairly easy to drink at the start.  By the last few glasses, it definitely got a little harder to drink but it was certainly tolerable."
