How Do You Take Care Of A Headache?

Right now, as I am writing these words, I am dealing with a killer headache and I think that the main pic for this blog is very fitting. That is how I feel sometimes when I have a headache, kind of blurry like everything is out of focus. But believe it or not, it got me thinking of ways to kill a headache. I have heard of  a lot of different remedies like, squeezing the part of your hand between your thumb and finger, it is supposed to relieve pressure some how. There is also the remedy of pressing between your eyes while your tongue is pressed on the roof of your mouth. Of course you could always take pain medication to make it go away, but most of the time I don't have any on me. So, that is why I am writing this. What is the best way YOU take care of a headache/migraine? I am talking home remedies that were passed from generation to generation... or something along those lines. So what do you do to tackle that cranial menace?
