Cider and rice are best, malt is good, it needs to be light - absolutely glorious is Mitsukan vinegar dressing, which is sweetened, salted vinegar which I have on hand as an ultimately skinny salad dressing.
One time I was just incredibly low and had the munchies and an epic wave of 'meh', and looking around, saw the vinegar and a little light went on on the internal dashboard. Turned out to work nicely, and I filed it as a trick for those bonks that don't clear with chocolate.
Today I got hit by a monstrous belt of melancholy (after seeing a pretty girl: I thought I was past being belted over the head by beauty, go figure). Got home, was staring moodily at the shelves and vaguely remembered it. Boing!
