I find that prepacking foods is wonderful! There's only so many quick-fix things that I enjoy that are convenient to take to work, so I've found that prepacking lunches that can be heated up at work are wonderful.

Shrimp scampi (shrimp sauteed in butter) is WONDERFUL!!

Mozzarella and cheddar cheese cubes are a good handy snack too. As for the water, it's strange at first, but now I feel strange when I don't get at least 80 oz. in per day.

Good luck!
