I believe that coffee can have terrible effects on some people. I cannot go near coffee when I feel down. I go from placid to wild-scary-manic lady within two cups of coffee. It acts on my body like a swift dangerous poison. I get cramps only when I've had coffee. I sometimes get these symptoms from too much chocolate too. However, I have no problems with caffeinated teas.

Give tea a try. Or, at least try to eliminate the coffee to see if it's the culprit. If that doesn't work, get a big soft blankey. Spend some time curled up in it while watching John Hughes movies.
