I am very bad about sleeping.
"Whatever a.m." for me tends to be something crazy, like 3 or even later. Then I have to get up at 5:30 to get my daughter off to school. After she leaves I get to sleep for an hour and then at 7:30 I get up with my son and get him off to school. If I feel particularly crappy, I go back to bed for another hour or two. This is not healthy.
