I'm a morning person, but I have to admit, at one point I wasn't. That's because I would stay up until 2am drinking my ass off, and having to get up at 6am to be at work at 7am the next day.

I don't party anymore though so I'm always refreshed and up early. I always up at about 7am everyday. Mon-Fri I don't work until 12pm, but weekends I start at 6am, so I have no choice really.
