My answer is from back before I was ill and had an actual sleeping pattern and looked forward to sleep (now it's torture trying to get to sleep):
Like you OP I am more productive at night, for me it's the early evening between maybe 6 - 9 pm. I could spend all day doing so little and then pump stuff out during that time.
But I am actually a morning person in the sense that I prefer that time of day; the sun breaking through the window and enjoying my morning tea / coffee.
Nowadays the entire day is miserable from start to finish.
I just woke up actually, time for a coffee.
