bowel preparation
"First colonoscopy at age 54 (I know, 4 years late). Read all the reviews and was horrified and dreading the experience.  Let me say, the negative revivews are overstated!  At least for me.  Solution isn't wonderful, but I found it very tolerable.  No straws, lemons etc... just chugged the 16 oz solution and followed with 2 16 oz glasses of water. Took first dose at 4 pm,  started working within 20 minutes,. Pretty well  done in bathroom within 3 hours.  Second dose was at 2 am.  Drank the Same amounts as first dose and went back to bed.  Didn't go to bathroom until 3 hours later. Not as much elimination with Second dose, as I was probably already "cleaned  out". I've had alcoholic drinks that tasted much worse than this!!"
