For me the night-time is the only quiet time to get work done (full-time job, family), but I still need to get up about 5:40 AM. I aim to get to sleep by 10:30 but usually work up until that point. I know I sometimes suffer when trying to fall to sleep, but I guess it's a trade-off I'm willing to make.
