"This is my fourth colonoscopy. In December I used a Prepopik Kit because I was given Suprep the time before and the taste was utterly disgusting to me. I told the doctor to give me something different because I didn't think I could take another round with Suprep again.  The person who said it tastes like Robitussin got it right on the money. Unfortunately for me, while the Prepopik tastes 100% better, it did not get me cleared out, and I'm now repeating the colonoscopy from December. The Suprep does the cleaning out job effectively. Just that taste....ughhhhh! I'm going to use the ginger ale suggestion and see if it helps."
