Man, I love sleep! I usually sleep 8.5-9 hrs when I can. My job disrupts my sleep patterns like Lise's....sometimes I'm up till the wee hrs, and sometimes I have to GET up at 0300. It just makes me sleep even more when I see a bed....
And once in a while an afternoon nap on a day off sneaks its way into my life....so delightful.
In my 20s I slept about 4-6 hrs a night; don't know how I did it.....
