bowel preparation
"It works even if you can't keep it down.  My colonoscopy/endoscopy was May 16 2014. Eat light meals like rice and chicken two days prior.  The day before, follow directions - I drank Coca Cola (for caffeine and sugar), Orange Gatorade and chicken broth.  Drink the mix as directed through a straw and hold your nose.  It tasted sweet and salty and I could not chug it down - took 15 minutes to finish the prep mixture.  Then 32 ounces of water.  I had nausea, chills and stomach cramps, but they went away in an hour.  The second phase did not go so well - I threw up the mixture.  But it still worked."
