My is surgery date is 04-04-2016 and I'm on second day of Pre-Op diet. I'm with you Tobysgirl already dying of hunger. :-( Mine isn't a total liquid diet, I am able to eat one lean Protein and veggies a day, and drink 4 Protein shakes, popsicle, broth, and pickles. I can do this but my stomach is saying no way!!! I counted it's right around 1000 calories a day for two long, very, long weeks.
