I'm with you on this. Like most people, I would like to consistently get 7-8 hours of sleep a night, but I've got two young children, a packed work schedule, and volunteer commitments. These days I'm operating on about 5 hours of sleep per night and I'm functioning fine. If I wasn't up at 5:00 am to get a couple of hours of work in before my kids are up at 7, I'd be falling behind right now. I'm probably making more errors than I would normally but they're mainly minor. By about 8:00 pm I get pretty fatigued and I may nap for 10 minutes at this time, to recharge for the evening. The work I am doing is challenging but for the moment doesn't require a lot of creativity, so the tradeoff between the sheer amount of work I can get done versus the decrease in errors is worth it to me at the moment. I do exercise pretty consistently however (approx. 4 times/week for 30 to 45 minutes) and I find this invaluable in terms of keeping me less stressed and more productive.
