I write like you did; early morning has a transcending blessing to the human brain. The first day I noticed this, I'd choose writing in the morning every single day, inspiration is limitless. At least that's how I see the early-morning writing routine.
About reading, I can read anywhere but midnight is the preferred time for me.
