Ungh...I have a headache, too. Developed about halfway through the concert last night (which was ridiculously awesome, by the way), and didn't quite go away overnight. Feel like someone has the left side of my head in a vise.
I'm taking some Goody's. Nasty stuff, but it does usually do the trick! The best things I ever found for headaches were Excedrin Quick Tabs - they dissolved in your mouth. They came out a few years ago and I bought up a bunch at first 'cause they were on-sale as a new item.
I can't find them anywhere now. I don't know if it's just that I was the only one who bought 'em or what. But it's a bummer.
I also have a headache. But I can blame mine on the bored meeting this morning. Ung.
