Thanks to all. Where mine will be done (Boston U. Medical center), the Golytely stuff is prescribed. Haven't heard anything about any pills.
The only other thing I have heard is that if you come up "clean", you might not have to have another for ten years. If polyps are found, another schedule may be needed.
Ekdog, I can't answer your question regarding cost. I'm one of the dwindling number of Americans with decent health coverage. This procedure is covered, as long as it's ordered by your doctor.
