Foods Easy/Fast to Digest..... plus bonus Metamucil question

Okay, time to start thinking about my next colonoscopy prep. To recap my post in November - I failed my last colonoscopy because I was not cleaned out enough (mainly due to not drinking enough fluids along with the prep).

This time around:
I am trying out a different prep (Pico-Salax)
I will try to get as much fluid into me as possible without actually bursting
I will do the clear-fluids for two days before instead of just one
and...
I want to consume foods that are easy/fast to digest one or two days prior to the clear-fluids days.

I think I'm now over-thinking this and getting myself all confused as to what would be quick and easy to digest (and still be somewhat satisfying so I don't end up eating my own arm by the end of it all). I'm thinking - cream soups, like cream of mushroom, cream of chicken? White rice, rice pudding? Applesauce?? What about yogurt (plain, not containing fruit or anything)? What about cereal that I normally would never eat - containing zero fibre? How about bananas? What else???

BONUS QUESTION - I take Metamucil daily (the powder-mixed-in-water kind). When should I stop taking this?

Thanks Q. Yes I do have broths lined up for the clear-fluid days. My husband even made me a big container of turkey broth when he made his batch of turkey soup after Christmas.

Oh, glad you brought up the headache... I don't get headaches from consuming foods I normally wouldn't eat but I do get them when I get too hungry. I'll need to take that into consideration.

I did start to do a search on low fibre foods and then started over-analyzing things so I wanted to see what people who have actually done preps would suggest.
