I went to a GI doctor this morning. I will be having a colonoscopy in November. In the meantime they gave me a prescription of Colyte. It has several flavors. Citrus Berry, Lemon Lime, Cherry or pineapple. I have heard this stuff is nasty. What is the best flavor to get? Can I take it with some other stuff or I have heard to put it in the fridge and have it cold. Two nights before the day of the test I have to take 3 five mg Dulcolax laxative tablets before bedtime. I just hope with all of this cleaning out I don't become dehydrated.
