I am going to try for a week or two. Having nearly 12 hours dedicated to work, I only have 4 exhausted hours in the evenings for eating dinner, spending time with my wife, kids and myself. If my wife and I split our sleep cycle into two 4 hour periods we can better spend my four hours of free time. The waking period between my commute and first sleep could be spend eating dinner, playing with the kids, and exercise. After my first sleep I can spend time with my wife, and study with a rested mind. Theoretically it seems like a good idea. We'll see how I cope after a week or two of trying.
