bowel preparation
"I had read lots of horrible reviews and was dreading this prep. However, I followed hospital instructions to the letter. A low residue diet for three days beforehand. Drank Moviprep as instructed starting at 6 pm. By 8 pm I was empty. Very effective. Slight stomach cramps for 20 minutes. In the midst of second dose now. Not a pleasant taste but it works and I get an excuse to eat Jelly Babies! 
I'm in UK and costs covered by NHS"
