I've been using F.lux on my macbook and my desktop for a while and can confirm it is awesome. I can feel the difference in the evening as my eyes are more relaxed from the usual strain of bright LCD monitors (I have dual monitors, which doesn't help)...
Additionally, I used to live in a basement with bad lighting and so I would go to bed at 3am and get up around 10am when the sun would finally shine in my room. About two weeks ago I moved into an apartment with plenty of natural light and I've been getting up at 7am and going to bed at midnight, as well as feeling significantly better and more alert overall
