I have to take MoviPrep the night before the procedure. Never done this before. I heard it tastes awful!! I know to chill it and I was also told I could add some country time lemonade mix in with it. Can I add enough of the country time lemonade and sugar to over power the awful taste or will it mess with the medicine properly doing its job? I have a bad gag reflex. Thanks in advance, this is my first one and I'm kinda nervous!!
