At the tender age of 46 (on Sunday) I am already a veteran of 5 bowel preps (4 colonoscopies and another procedure). They are not fun, but the worst part is drinking the prep medicine. I never used the Golytely, but I did use Phospho Soda for my first procedure. Rather than having to drink a nasty liquid there is a pill-form bowel prep medicine called Visicol. I used it the last four times and found it to be a much better alternative. Now, it's the only way I'll do it.
