It may have been the grain. When I was watching the Superbowl with my buddies, I decided that since it was a special occasion [I know not for everyone :) ]I was going to eat pizza. I ended up eating a half of a large pizza. By the time I had finished, I develpoed a terrible headache. It was very similar to a bad caffiene withdrawl headache- the kind that doesnt stop with medication. I have eaten ice cream with no ill effects, so I would say grain causes more of a reaction than dairy. Your poundcake situation sounds like what happens to me. We've all kicked the Carb habit, but for a long time we will still be addicts. When I eat some carbs, it always seems like i end up binging till I get sick. Ry
