I'm the same way. I would actually prefer to do it at night but I don't because I have a hard enough time sleeping as it is. I never feel like it when I first get up but I know if I wait and do it late it will just make my bedtime that much more stressful. I'm like that with everything, though. It's nothing to me to go out at 2:00 am and shop for 2 or 3 hours.
I had to get up really early today and I'm so sleepy right now I can hardly think, which is unusual.
