Yeah I had a schedule like that when the kids were very young but it caught up with me, frankly. Having the computer be the first and last thing I interacted with every day was not great for my mood either.

Granted, I do need to take a break from that schedule every so often. If I catch myself being unfocused I just go to bed.

Also, the first thing I work on is usually a high leverage project that excites me. Reading news or answering emails (things that can affect my emotions) are usually avoided during that time. Usually.
