Financial talk

Did you work 50, 60 hours a week (for longer then, say, 4 months), and how was it? Did you feel like a zombie after a while, and need to quit for normal hours? Or was it tolerable (though unideal obviously)? How'd you cope, is really my main question. I'm considering doing this - working 12 hours/day, five days/week; probably semi-hard to hard labor, to cut out (personally) the customer factor - so I can get together some more serious cash. Fall-back money. Anyway ... any experiences would be greatly appreciated. Thanks
