I have been getting up at a little after 4am for years now, and every morning I have the same reaction when the alarm goes off. I'm shocked. Shocked that it's time to wake up. Shocked that those five hours went so quickly. I've been doing this for years, so you would think I'd be used to it. I'm not. I was just as shocked this morning as I was on this date seven, eight and nine years ago. It got me thinking.. Does anyone get 'enough' sleep?
