For those (like me) with 12+ hours: I bet you're not getting enough sleep. Besides f.lux, try melatonin. A tiny dose of 300mcg has helped me a lot to regain the desire to sleep (which was always my problem).

Blue light is indeed the reason why some are still active at 4am. The problem is not that you don't like to sleep; you don't want to sleep, because of your level of melatonin.

Lots of good comments in [1], [2], [3]. Search for f.lux and melatonin on HN and you'll see hundreds of similar discussions.
