I did that for just a little while, when going through a divorce. It was kind of fun. I had what I needed at work: shower room, place to sleep, Internet access.

A fridge to keep groceries and a microwave oven too.

I ate canned food, combined with fresh vegetables.

I discovered that using a microwave, you can easily bring water to a simmer in a plastic container, and by that means, you can cook pasta very nicely. (I'm sure it saves energy compared to stove top pasta boiling. It takes about ten minutes (same) and the wattage of the microwave is not only lower, but you don't use it on full power.)

Toaster ovens help too. If your office doesn't have one, just go out and buy one. You can revive a store-bought frozen casserole dish in one of those things.
