the colonoscopy prep that i did was good i took 2 dulcolax at 12:00pm then at 2:00 i started to drink gatorade 2 32oz bottles mixed with 238 gram bottle of miralax 8 oz every 25 min until it was almost gone (i couldnt finish it i was too full)then at night before bed 2 more dulcolax you cant use red or purple gatorade i just know this was so much better than the jug stuff

My prep was identical to charlenef's. It supplements the electrolytes you lose by having 5 hours or diarrhea. I still had a pretty fierce dehydration headache, but I think it could have been worse without it. The reason why you can't use the purple or grape sports drinks is because purple food stains your colon. There should be something in your reading materials about staying away from purple foods and seeds and anything else he doesn't want you to have.

My husband did Fleets and said it was the most horrible thing he'd ever swallowed. We've come a ways since Fleets was the only thing you could take. There are better things to take. If he won't agree to the OsmoPrep which is the best, ask him about the Miralax.

I agree with flowergirl2day's advice to check with your doctor about anything you are taking.
