Prayers for Jessica, Susan...
The colon prep that used to be the standard was "Go Lightly" which is primarily polyethylene glycol... which is what, plastic? On my first colonoscopy two years ago I drank that and it drove my blood pressure up so high I nearly had a stroke. My head was about to explode and I literally felt like I was dying. They had to give me injections to bring my blood pressure down before they could do the scope. Maybe your mom had some reaction like that too, Susan? Now my dr. won't even use the Go Lightly, so I guess many people were having problems with it. This time I will be drinking 64 ounces of Gatoraid with Miralax, like JeanieG mentioned. Oh joy... fun day.
