Yes, especially now. I just started a new job that requires me to be away from home 10 to 10-1/2 hours on weekdays. The work is interesting, but I have to adjust to new procedures, people, environment, etc.; steep learning curve = fatigue.
My kids are home and my husband snores; when my son's away, my husband can move to another bed, but in the summer that's not an option. So I'm kinda sleep-deprived.
I'm not so busy socially these days, but when I am, that takes a lot out of me, too. These days I come home, eat dinner, do a little email and foruming and watch something entertaining.
And I'm starting school at the end of the month. People my age are retiring and I'm returning to school. You bet I'm tired.
