I agree on the Golytely. I could only finish about half of the prep. Just the idea of being told you have to drink the whole gallon in a short time, doesn't help.
The Phosphosoda is even worse. You don't have to drink much of it, but no matter WHAT I mixed it in, most of it came right back up. Even ginger ale didn't help.
There is some kind of a pill or capsule that some Drs. tell you to use prior to colonoscopies, but I forget the name of it.
I've never been offered any pills.
