bowel preparation
"Well, just finished going through the first portion of the Suprep.  I must say, it was very difficult to drink.  The taste is awful. I had to put a cup with Gatorate next to the cup with the preparation, so I could drink a sip between each time that I took a drink of the Suprep.  But it really has worked.  I was terrorized with fear, but I haven't had any cramping or stomach ache at all, no nausea, no headache, and except for the terrible taste, the experience hasn't been bad at all.  This is my first time getting ready for a colonoscopy, and I was glad I found this site before I started, it eased all of my fears by reading all the other comments.  Thank you for having this site up.  It helped me a lot.  Hope I am able to help someone else."
