I'm ADD myself, and a night owl most of the time, and you've got me wondering if I get into a groove in the evenings because I'm less hyperactive and more relaxed. There's a kind of peace to the night time for me. Maybe it's the lack of outside pressures, maybe it's tiredness, maybe it's something else, but I find it weirdly comforting.
That's interestingly enough exactly the reason why I like to get up at 4-5am and work before anyone else gets up. It's calm, no distraction (even less so than late at night) and I'm well rested for the night.
