I loved it but my life didn't accommodate it. It was much easier on work days because I could sleep both ways on the train, one nap in the middle of the day, and then make it through family duties at night before I needed another nap. My wife didn't enjoy the scheduling difficulties on the weekend and it's not something you can switch on and off on short notice (takes about 5-7 days the first time and 2-3 days to start back up). There's a couch at my new job and I'm considering starting up again.
