I need more time!

In the most literal sense. My hubby can get by with about four or five hours of sleep. I need eight or I'm comatose all day (even after coffee). Are sleep requirements genetic or is there some sort of training I can get to learn to sleep less and still function? Imagine the things I could accomlish with three or four more hours a day. Hubby would suggest that I spend less time on blogging and stuff but we ALL know that's not gonna happen. I won't give up my time with Girlie and I am simply hardwired to read books all the time. When will I watch the four hours of "24" I've got on Tivo? When will I see even one of the movies that won a Golden Globe? I need more time! Any suggestions?
