This is an honest question: how much exercise do you get? More general question: Any insomniacs out there that also happen to get cardio (running, yoga, whatever) at least 3 times a week for at least 30 minutes each time?
But, no, I haven't been getting enough serious cardio exercise; thanks for the reminder. Thinking back to my time as a climbing instructor, I think my sleep patterns were a lot better. Still irregular, but better.
Maybe it's this? It's very common among hackers, and easy to confuse with insomnia. Well, it's effectively the same if you have to wake up early.
