I just thought of one last thing... a lesson I learned while doing research with a professor this summer, but it applies equally well to the school year.

When work piles up, it sometimes feels like all I do during the week is eat, sleep, and do homework. For five days out of the week, eating feels like my only pleasure/distraction from work, and for that reason it is an even greater lure than it would normally be.

So I make sure that I take at least fifteen or thirty minutes each day to do something that is purely pleasurable - talking to my best friend (about anything but school), vegging in front of the TV, reading a "fun" book, giving myself a pedicure, whatever. Just as long as it is utter bliss!

And that way, food stays (in my mind) as it was meant to be - sustenance. Purely sustenance.
