bowel preparation
"Just drank first 16 ounces- couldn't finish it all- drank first 16 ounces of water- the prep makes me gag and vomit some.  Stomach is hurting and I'm so queasy.  There has got to be an easier way to prep- this my 4th colonoscopy so I knew what was ahead -   Can't wait to be sedated and have this be over."
