bowel preparation
"This is the 4th colonoscopy I have had. I WILL NEVER PREP WITH MOVIPREP again. Tastes like moldy salt water with a twist of moldy lime. I literally gagged trying to get this down and yes I used a straw. 

It is expensive!

If you have an early morning appointment, you are up 1 a.m. (For me) to do Part 2. 

No prep experience is pleasant, MoviPrep is disgusting."
