Suprep Bowel Prep Kit
"Surprep is the most horrible tasting colon preparation that I have EVER encountered.  I had to use a straw and gagged and my eyes watered after each sip.  I see no reason for anything to taste so bad.  I have had previous colonoscopies and never had a problem with the prep solution.  My new goal in life is to warn everyone about how horrible this stuff tastes and get them to ask their doctor for an alternate solution."
