bowel preparation
"I took my first dose as directed at 6:00pm.  Didn't taste good- but I chugged it down and drank 32 more ounces of water.  Had chills and lots of stomach rumbling- but no BM!  And now it's almost 6 hours later and just chills and rumbling but still no action.  Supposed to take second dose at 4:30am , but I'll move that up to 3:00am.  Has anybody taken the first dose and... nothing?"
