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.
Oh, speaking of chocolate, I've been reading articles on chocolate and neurotransmitter symptoms (such as http://www.chocolate.org/chocolate.pdf
among others) and I'm trying to figure out which chemical component exactly I'm addicted to. Here's another good one: http://www.chocolate.org/pea.htm
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.
