What kinds of stuff does your pre-op diet include? I've been on mine for a week and it includes cream Soups, Jello, pudding, popsicles...low fat/sugar free. I still have another week of it. Actually as of next Tuesday, I go on Clear Liquids only.
It's not lots of fun but it's managable...I promise. You can do it. Once you get started it'll come easier. It'll be over before you know it.
Hang in there!
