I put in months on a startup when I could set my own hours, so I stopped using an alarm clock. I'd usually get a coding burst from 9pm-1am, go to bed, get up around 8:30 the next morning. I took a dayjob to help make ends meet for a while, and had to go back to using an alarm. It's been very, very bad for me. I need to get to bed earlier, but that's not always possible. The exhaustion and pains are coming right back. A natural sleep schedule. That made a huge difference in my health.
