Hey Shanda!
I'm having surgery in 3 days too!
I've cheated somewhat too (just a little); however, my surgeon is very conservative so it's only been vegetables and protein-- no meat. But I've had a bit of a saving grace, as my pre-op diet coincidentally began with Ramadan, so I've been fasting through it and only eating after sundown. This means that when it's 8ish (the times for each day correspond with one of the five prayer times), I can cook a stirfry with a little bit of olive oil, soy sauce, and veggies and those things usually fill me up.
However, surgeons say that you can have unlimited amounts of sugar-free jello, pudding, and popsicles, and if yours says you can these things can help you trick your brain into thinking you're eating normally. You can have as many as you want (if your doctor says so too) and you'll be okay. It's been a little tough for me too, and I've been wishing that time would go faster, but remember that 3 days is nothing compared to how much time and effort you put into getting the surgery.
Also, I lost just about as much weight as you have, I'm down from 315, which was my HW and the weight pre-diet down to 294.
Good luck, please come back and tell us how everything goes with your operation!
