Ask HN: Have you shifted your hours for better productivity?

I've been working a full-time job and trying to get some Web development done.

My typical day was something like: - Wake up at 7, get the kids ready (one off to school) - School drop off by 8:30 - At work by 9 - Home by 6 - Family time, dinner - Work on Web project from 8-midnight.

Needless to say, those last 4 hours aren't the most productive! Recently I've tried going to bed at 9:30 and up by 4am. A good night's sleep seems to be working. Anyone else becoming an early bird?
