Timely article, after listening to 4 hours of constant firecrackers in the neighborhood from 10pm-2am, I did not fall asleep until 6AM; thankfully today is not a workday. At least once a month, and in the past year more like once or twice a week, I can't fall asleep until right before I have to get up. Yet other nights I do exactly the same things and sleep 7 hours or so. When my body is in the no sleep mode (which I presume is an excess of cortisol) no matter what I take nothing will put me to sleep until that wears off. Working in a high stress environment writing code and managing a team in something with CEO level visibility (in a big company) I am sure its stress related. I can see why Michael Jackson went to ridiculous extremes trying to sleep (and paradoxically not actually sleeping). It's a miserable experience to trying to function one hour of sleep and do anything complex.
