...Late-night Boredom Tactics...

Working nights means I spend most of my time staring at the clock, waiting for something to happen. The radio stations are all asleep too, leaving me with nothing but silence and my thoughts. Tonight I started watching old reruns of a sitcom that's been around forever just so I could hear someone else's voice... Is this normal? Am I just supposed to sit in the dark and wait until dawn comes? Any tips for staying sane during these lonely hours?
