An alternative to #2 seems to be to set your alarm in line with sleep cycles. Work out how long it takes you to go to sleep (I'm actually not sure how you do this, 14 minutes is average and works great for me), add 6 hours or 7:30 (or some interval of 90 minutes), wake up at the resulting time. I do it using DoubleTwist (which defaults to the 14 minute to get to sleep thing), but it's easy enough to work out and works really well.

I think the point is that the light signals your body to stop production of melatonin, waking you up naturally.

That's interesting. Something I've never thought about before.
