What I did do, was unplug for a month. I went to stay with friends, in Australia. They're still building their house, and I spent time putting wiring and plumbing in for them. Needless to say, electricity was limited, and there was minimal (if any ) internet.
I didn't speak to anyone on this side of the world, or any side of the world. It was good.
I am now back writing a grant ('cause you don't let a deadline pass...).
