Wow, that sucks. :lol
Its true though, the few times in my life that I've had headaches has usually been because I spent excessive amounts of time staring at a screen. One time when I had a headache I tried lying on the couch and watching TV, but it got worse. I ended up going outside and playing soccer with a couple friends, headache went away after about half an hour of fresh air and physical excercise... and not staring at a screen.
