bowel preparation
"This is my 4th colonoscopy/bowel prep:  First dose and fluids went down ok despite some nausea.   Second dose made it down followed by some water.  But 20 minutes later when sitting on the throne the nausea welled up and I started vomiting.  Did manage to catch some in the waste basket next to me.   Dr. did not complain about my preparation so I think it was fairly good despite losing most of the second dose.    However the Prepopik I took for a previous prep was much easier on me and was also deemed a good clean prep."
