bowel preparation
"I took the split dose at 8:00 pm within a hour I was sick to my stomach.  At 1:30 I started throwing up while sitting on the toilet.  I have not felt so nauseous in a long time.  At 2:30 am I was scheduled to take another dose which I promptly started throwing up.  I was still very nauseated until the colonscopy at 7:30am.  I now am scheduled for another colonscopy because the bowels were not clean enough in 5 years even though there was no polyps or any other issues.  I will never have another colonscopy because of my experience."
