Mate and coffee both make me crazy, black tea a little less so. I save them for emergencies. I can do green tea and even puer (though I usually cut it with ginger or jasmine or something). Somehow the caffeine in chocolate never seems to affect me.

Does anyone know any good non-chocolate sources of phenylethylamine or theobromine? Or maybe it's the tetrahydro-beta-carbolines? Something...
If anyone's got any chocolate knowledge, please share.
