I get headaches sporadically, usually if I haven't slept very well, or if I stare at a particularly bright screen first thing in the morning...like my iPod's. A lot of the time I just ignore it, although if it becomes unbearable I'll take soluble tablets, since I can't swallow regular ones. I prefer not to take painkillers, because the caffeine in them does strange things to me and I generally feel even worse once they wear off.
Most of the time I can just take my mind off it though, by watching something, playing a game, or immersing myself in a book. I generally don't listen to music.
