I sleep around 10 hours a night. Over 20 years ago, I was diagnosed with bipolar disorder. My psychiatrist at the time recommended that I setup a rigid sleep schedule, to ensure that: 1) I regularly received a sufficient amount of sleep 2) My sleep schedule was consistent For people with certain conditions (that probably don't apply to most HN readers), ensuring a sufficient but not excessive amount of sleep is very important. For bipolar disorder or major depressive disorder, inconsistent sleep can really throw you off. I take medication, but I've noticed over the years that my condition is much better when I get a solid 10 hours of sleep. It seems a bit silly to hipsters in SF that I'm in bed at 8pm, but it keeps me stable and functional.
