I'm diabetic and am scheduled to have a colonoscopy next month. I have been having bowel issues for quite sometime, hence the colonoscopy, with diarrhea almost every day with resultant dehydration. What I'm unsure about is what prep beverage should I mix the Miralax with. I've been trying to find palatable sodas like diet ginger ale. I'm afraid to drink Gatorade because it contains sugar. The nurse where I go to the doctor thought the gatorade w/ sugar would be good since I'll be experiencing diarrhea, and will probably get dehydrated, and the sugar will help, but I'm afraid as a diabetic that all that sugar will cause me to be further dehydrated. Any suggestions from anyone else who is diabetic and had a colonoscopy. What did you drink with your prep? Thanks in advance.
