bowel preparation
"The stuff works, no question there.  But the taste of it is absolutely horrendous and I'm due to drink the second round in about 30 minutes and am full of dread.  When I started the first one, I was immediately thinking that I'd have to call the doctor's office and say I couldn't do it.  There is simply no excuse for something to taste like this.  My upper lip was sweating, I was shivering, the taste was enough to make me gag though likely not vomit.  Other preps have worked just as well in the past but did not taste this bad."
