bowel preparation
"I took the medicine at 6:00pm and nothing happened for 3 hours and then it hit and I kept running to the bathroom.  The first dose wasn't bad to get down, didn't really taste it.  I was told to suck on a Hall's cough drop first and it would kill the taste.  It did, but I had to take another dose at 4:00am and even though I used the cough drop, the medicine was terrible.  In both times I drank the 2 16oz of water.  The 4:00am dose worked faster it only took about 30 minutes.  The good news was my Dr said I was totally clean and don't have to do this for another 10 years!  I didn't have to "fast" just had a light breakfast, lunch and dinner the day before, and nothing the day of the test."
