I don't follow, whatever you do from 7:30-9:30 I used to do just as well from 22:00-24:00. Family obligations unfortunately made splitting the work day in half like this very hard so I now start earlier, feel tired all day and am much less productive. I'm just not a morning person, before 9:00 I just feel miserable. It doesn't matter if it is work, exercise, reading or studying - nothing feels right.
