I'm with nicholas, buddy...The job is fantastic, but I'm madder than hell at the business. So yes, I'll complain because it allows me to vent...in turn leading to a cooler, more rational way of thinking -- which is what we all need to end this death-spiraling career.
Enjoy your time off, as you'll be back flying in no time. But also use it to your advantage -- do what you can to make your job in-waiting better than when you left.
