bowel preparation
"This will be my first colonoscopy.  I used many hints from the reviews here.  I chilled the solution and mixed it with part water and part 7Up.  It tasted like salty cherry soda.  I divided it into three cups and used a large straw.  I sucked on a lemon slice between each drink.  I then drank all the extra water in a short time.  It does work very fast.  I started at 5:00pm and was done by 10:00pm.  I had no headache, chills, cramping or nausea.  The second round was no trouble either.  I am very glad I read reviews on here first."
