Is there anyone working US eastern hours?

I am thinking of staying in HCMC or Hanoi or Bangkok for two months, working US eastern hours. My work load is very light, perhaps four hours daily, sporadically. Is there anyone there with similar schedules? How do you feel working from 10pm, being up at 2am or done at 2am?

Would HCMC or Hanoi be better at 6am? I've been to both cities , but never been up at that hour before.
