You are very lucky to have a strong circadian rhythm that doesn't require light in the morning then. Not all of us work that way. If there is no light in the morning I find it very hard to get up and function. Where I live, if we adopted permanent summer time the sun wouldn't rise until 9:45 in the dead of winter. I couldn't handle that many hours of complete darkness at the start of the day.
