You won't push too much.
Get the dark out of the way whilst you feel good.
HUGE mental lift as day light appears, which carries you through most of the day.
I started my paddy at 6pm, theory was get a few hours in day light, relax, calm down, build in, do the night, then you just have the day light left without the night stage hanging over you.
TBH 30 odd hours awake isn't such an issue when you get used to it.
