In the past I tried creative night shifts too, sometimes till 3AM but in the morning I was wrecked.
So what works now: I go to sleep same time as my kids and wake up much earlier.
Benefits:
1) kids get good habit going to sleep at the right time
2) you get a proper sleep
3) at least my morning mind is much more fresh after some exercise
4) your creative wandering is time limited by how early you wake up - that is most difficult especially in the winter, but it is just a matter of habit and doesn't sacrifice health so much.
5) I am unlikely to procrastinate in the morning if I wake up with a planed task in mind
