bowel preparation
"Well, it did what it was supposed to, but tastes so bad.  I got through the 1st liter ok.  I gulped it down.  Bowels were moving about an hour after the first 8 oz.  I had to drink a second liter several hours later and just couldn't do it.  The taste is that bad.  I threw up probably half a liter of it.  Anyway, it cleaned out the bowels."
