I use gatorade. I actually got powdered gatorade to keep at work in a drawer. I can't imagine anyone trying to use it in a drink.

Check around work. There has to be a place where you can stash some stuff that you can toss in the microwave. Keep in mind, you can microwave just about anything these days. Bring a tupperware container, fork, knife and spoon, and a few boxes of some stuff you just add water to and microwave, and you're good for the week. Get a handful of powerbars to keep at work, and those will be handy snacks for you. Then the only thing you need to bring in are small things like bagals- those weigh next to nothing.

Don't give up- look into all your options and talk to your boss too.... they may have some ideas or a place where you can stash your food.
