As everybody witnessed on PC SZ I get very agitated due to sleep depravation. Or if I get absolutely no sleep, for some reason, I do a little better mood wise. One of the tricks I perform that helps me fall asleep is to watch a movie i've seen a million times, that isn't suspenseful or action packed like Hamlet, Harry Potter, Sopranos, or the Godfather. It helps my mind to just relax and passively watch something mildly entertaining.
