bowel preparation
"I have a colonoscopy every three years so this isn't my first rodeo!  I have successfully  used Golytely and Suprep in the past.  This time, the nurse wrote a script for Prepopik.  I was on clear liquids the day before the scheduled colonoscopy.  At 8pm I consumed the first packet of Prepopik mixed with 5 oz of water and chased it within 2 hours of 50 oz of water.   I waited and waited but felt nothing, not even a little toot!  At 4am I took the second packet mixed with 5 oz of water.   I chased it with 24 oz of water within an hour.  I waited again but felt nothing until 7:30am when I had a very small movement. My stool never cleared more than normal diarrhea.  I was forced to cancel my 10:30 am colonoscopy appointment.   Never again!"
