I know exactly what you mean. At the end of the summer I'm fried and stressed. For the past few years I've tried to work as hard as I can in the summer when I can make a lot more and pretty much take off the slow season. I work maybe 70-80 hours a week in summer and maybe 15-20 during the slow season. It works pretty well for me. It gives me a chance to take vacation, do personal projects, spend time with my wife, and recover from summer.
But this year the summer is lasting and from about August 15th to now I haven't wanted to look at another AC. I need a break.
