@barbaradh During my prep, i did eat green jello, along with drinking lemon-lime gatorade with miralax, and some apple juice and lots of water! everything was so sweet! and the chicken boullion was too salty. My prep was rough - 6 Dulcolax and 2 bottles of Miralax in 3 bottles of Gatorade - i was pooping clear Gatorade by 3pm and gave up on the rest after that as it was making me ill. The procedure went fine- and no polyps or other problems, so never again!!
For all the advice to "finish your prep" - you know your own body and judge accordingly.
