Earlier quoted context omitted.
When do you get in though?
8:30. My hours aren't all that terrible, but after burning the candle at both ends for the better part of a decade of grad school, I'm a little worried about burning out.
You didn't mention riding after dusk as a problem, but there are plenty of good bike light options available now. LEDs and batteries have come a long way in the last 5-10 years and small, rechargeable lights are now powerful enough to provide adequate lighting for nighttime commutes (some are even bright enough for daytime use - so cars see you better).
