bowel preparation
"First timer here.  Like a comment above, I'm 54 and doing this for the first time.  My anticipation (and fear) about this was completely unfounded.  I expected a most vile drink and explosive diarrhea for hours.  Got my slices of lime (suggested somewhere to get the taste out of my mouth), flushable baby wipes, and charged my cell phone to have something to do).  The taste was bad, but so is taking shots of Tequila!  Drank the other two 16 oz glasses of water within 10 minutes.  In about 20 minutes, it started.  I was only on the toilet for about 45 minutes and went back every 20 minutes.  It was pretty much over in 2 1/2 hours.  And, unlike being really sick, it wasn't that bad.  Round two was less of an event!"
