Water + Beer + Water = OUCH!

I had lunch yesterday at The Taste of Chicago and, since I preferred spending my tickets on food*, I bought a bottle of water instead of having my customary Coke with lunch. Later in the day I took a free Bud Light off the beer cart. Then, to save calories, I had only water with dinner.

And by bedtime I had a headache that didn't respond to painkillers.

It wasn't debilitating, just painful, so I know it wasn't a migraine. I suspect it's because I skipped the Coke -- and the caffeine -- at lunch.

*I had fried cheese ravioli from Harry Caray's booth, peach cobbler from B. J.'s Market and Bakery and, in a bow to tradition, chocolate-covered cheesecake on a stick from Eli's. I only regret the ravioli. It was very bland. And, to borrow from Woody Allen, it was such a small portion!
