I've never been a morning person, either. For most of my life, I wrote at night. I did so when I lived alone, and I did so for most of my married life. For me, the sunrise was always a beautiful thing to see. . .right before I went to bed.
And then we downsized, and i lost my office for a couple of years in the process. This, and other responsibilities meant I had to write during the day, and had to start as early as possible. I found I could do it well enough, and this surprised me. Then we upsized slightly from our downsizing, I got my own, nice office back, and the family responsibilities went away, but without any real conscious thought, I never went back to writing at night, except in an emergency.
I have to sleep sometime, and found that sleeping at night gives me more time to get out of the house and do things during the day, while still getting in my writing time.
I still miss the quiet, the silence and solitude, the peacefulness, of writing at night, It's a different world, and I like it, but I don't know that I'll ever go back to it.
My desire has always been to have a schedule like Ben Franklin did. I'm not sure how anyone manages to get by on fiver hours sleep, or less, but he did, and his daily schedule sounds like something only a man of some special nature could keep up for long, but he managed it for years on end. It's simple, but remarkably challenging, I'd think. You can find it on this list of writer routines:
