I am having some trouble keeping reasonable hours with RTW. 3.5 - 5 hours at a stretch is normal

I occasionally go without enough sleep, but when I get tired I don't enjoy it as much as I would when I am sharp. I tend to auto-calc. too many battles when I'm tired and I quit and get some exercise- meaning I get something to eat or do some housework- my wife is 1/2 Sicilian, and I have learned not to let games suck up all my time.
