I know this post is waaayyyy too late since you were prepping last night, but I wanted to chime in about
the MoviPrep.
First, I hope you made out okay last night and this morning and I hope your scope went well!! 
Regarding the bowel prep, I actually had a much easier time with the MoviPrep than I did with OsmoPrep (horse pills - all 32 of them) that I used in 2008. Those things were outrageous!! Anyway, my GI gave me the go-ahead to substitute citrus flavored Vitamin Water for tap water to mix the MoviPrep. So I did, and stuck it in the fridge that morning. By the time I had to start my prep that night (around 7:00 p.m.) the MoviPrep was nice and cold and really easy to get down. There was a salty/sweet aftertaste, and by no means was it delicious, but it was completely palatable. I had no side effects (other than a teeny tiny headache) and the bathroom visits were must less...violent is the only word I can come up with...than they were with the pills. I was running clear by the time I finished the first dose and was able to get a few good hours of sleep before the second dose. I couldn't finish the last 8 oz because I was so stinking FULL! But I got a 2 thumbs up on the prep from my GI so I was good to go. The biggest plus for me was that I was DONE GOING before I left the house the following morning. With the OsmoPrep pills, I was literally still going as they were walking me back for the procedure. That was horrible!
Anyway, sorry for the ramble. I just wanted to share. Have a great day!
