I've been using F.lux for a few months, but had "solved" my sleep problems prior. The secret was to ensure my computer was off 2 hours before my intended sleep time. Interestingly I could sit in from of a 55" LCD television for that time period instead (with the brightness dimmed a bit.) Within two hours I would go to bed and be asleep within 15-20 minutes. As a self employed entrepreneur since I dropped out of college some 5 years ago or so, I had immense difficulty with my sleep patterns until late last year. 24 hour cycles, waking up at midnight, every possible worst combination imaginable. Based on my own personal experience over the years I suspect light intensity and prepping for bed time fixes 90% of the problems -- assuming you are not a user of any type of narcotics or stimulants, prescription or otherwise. To a lesser degree changing my diet and pulling out all added sugar at 95% of dairy probably contributed positively as well.
