@SG Weirdly, the stronger coffee helps me avoid them. It has to be insane strong, though; espresso rather than coffee, really. (Bear in mind, I also have ADD, so various stimulants sometimes soothe/balance everything out rather than causing the jitters. It's the entire premise behind ritalin, weirdly enough.)
I can deal with espresso and I can deal with weak, but damn the middle of the road brews (especially light roasts) always tastes horribad vile and acidic and harsh to me.
