Yep, here I am at 2am, feeling super guilty about being awake. I can generally stick to a normal pattern of sleep for a week or so, but I eventually have one evening come along where I end up staying up late. I tell myself it's out of necessity for work or other catch-ups, but really it's just a natural inclination.

The worst part about not being a morning person is the loss in communication skills during critical morning meetings, etc. The parts of my brain responsible for solid verbal/written skills are just not up to speed yet. Lots of coffee turns me into a highly alert rambler. It's better than nothing I guess.
