I've set this post to publish at about the same time I'm getting up today: 3:00 am. This is because of a bunch of jobs at The Store that need doing, which have to be done very early before the associated departments start doing their thing (i.e., before they start handling food). The extra money associated with the overtime will be nice, but 3:00 am is just an awful time to get up.
So: what's the earliest you can get up where you're not thinking along the lines of, "Oh crap, I'm up now. Ugh ugh ugh."?
