I have issues with getting more than about 6-6.5 hours of sleep before my back is sore enough I have to get up. I try to make the most of it. Like others have said, definitely get more sleep. Also, move more. Go for a walk. If you don't have time, consider getting a treadmill desk, and shift your workflow to sitting and standing. It takes some getting used to, but that has made a world of difference for me.
