Some nights, it's just impossible to fall asleep. Most of them, I just try a bit harder and soon I'm sleeping like a baby. But others are hopeless. I try to sleep but don't feel tired. After a few hours past midnight I start to feel tired but still can't sleep. Those times, when it feels like I'm gonna stay awake til sunrise, I check if it's full moon. And those times, it always is. There is a connection. Right now it's 99.2% full moon.
