My NUT was suppose to give me enough food to last until Sunday, I have 1/2 day of food left, I have been on an 800 calorie diet that i have followed faithfully...the food was purchased from my Surgeons office.....im 3 hours away so now what do i eat....Surgery is Monday! Its a high protein, low carb, low sugar, high fiber diet and no protein drinks included...

Well....things that are "high protein, low carb, low sugar, high fiber " and within your 800 calorie limit.

Try to get some protein drinks, EAS ready made protein drinks are pretty good they are 4 packs for $5 @ Walmart and target.

Why no Protein drinks? What kind of items did you purchase from them that you can't get at a regular store?

I'd recommend lean chicken breast (no skin), Greek yogurt, hard-boiled eggs, avocado, shrimp, salmon - things like that.
