Yep. This isn't massively different from what I did when living in the states; I've always found myself far more productive at night when there are fewer distractions. Now I just get more sleep since I don't have to report to an office in the morning.
12pm - 2p: Wake up (no alarm unless I have an early appointment)
2p - 6p: Run errands, exercise, meetings/calls with any APAC clients
6p - 10p: Hang out with my wife (who works a traditional 9-5 schedule), go out to dinner, meet friends, etc.
10p - 5am: Work.
5a - 6a: Read to wind down for bed
6a-ish: Sleep.
