I think some sleep might actually be your best bet... you don't have to sleep sleep, maybe a couple hour nap might be good enough. My eyes never start rolling around but I do get headaches if I watch too many movies or play certain games for too long. If that happens, I usually take some Advil. If it's really bad, I take Advil and take a nap. But just a warning, sometimes when it's really really bad, the nap makes it worse... but since you don't say your head hurts, it might not apply to you.
