The things I ate during my last prep were:
Chicken broth (low sodium)
Jello, but nothing red or purple.. I went with blue, but yellow is probably a better idea. It was so weird going to the bathroom and having a bowl full of blue liquid...
Gatorade (again, no red or purple)
Ice pops... These were a lifesaver for me.
I started my liquid diet two days before the scope to make the actual prep easier, and it did- I had nothing but liquid coming out of me that night. But it was really rough basically starving myself and I got pretty sick on the first night. Funny, ever since then my appetite has been terrible, I think my stomach may have actually shrank in addition to the prep making my flare worse.
