I like to stay up late at night and sleep later in the morning, but I still prefer to sleep when it's dark and mostly be awake during the day. Just not too early in the day. Seems to work best with my circadian rhythms. I dread tomorrow because I slept late today and then also had a long nap. So Im wide awake but I have to get up at 6:30 tomorrow to get ready to leave for school by 7:45 or so.
