"This is my third colonoscopy and my first time using suprep and it was very thorough. I was interested in this one over the ones that have you drink 64 oz which is too much so this was a plus. I wish I would have seen the suggestions on adding a bit of ginger ale or some peach mango crystal lite . I did try taking it through the straw but there is no easy way if you don't add something else to it to not have that distinct cherry cough syrupy taste.  After drinking so much I was a bit distended and nauseas but that passed after 15 min. I was chilled as many indicated so I wore a sweater and winter coat. Problem solved. Because I had a low fiber diet all week my second half produced only clear liquids. Check internet for diet."
