Summer insomnia

I estimate that we have maybe nine weeks left of Summer and it can't end soon enough. The rainy season is coming to a close and the heat and humidity are now becoming less and tolerable and will only get worse. The problem is that now I cannot get anywhere near enough sleep. I'm finding it harder and harder to get some shut eye. As uncomfortable as the days can get here, the nights are worse. One good thing to come out of Summer so far is that I've lost a small amount of weight through good eating.
