I probably get a total of 3 hours of sleep at night spread out over 8 hours. Just can't stay asleep for any amount of time. It's been months since I have been able to sleep longer then 1 hour at a time.
You want to talk about time spent at a desk, I spend 40hrs a week at a desk at work at probably 40 more at my desk at home. Hell that's where I get most of my 1 hour sleep! lol
