YMMV, but I often find myself in a weird state where it's easier for me to "hunker down" and do a couple more hours of work (because I'm already in the flow), but I'm too exhausted from work to do personal projects around the house... If I'm really feeling exhausted in the afternoon, I'm really good at taking a 25 minute "power nap", my mind goes from slightly foggy to crystal clear, and if I take it well before 5pm my sleep for the night is typically not impacted at all. It's taken some training to get to the point that I can quickly shift into sleep and then snap out of it, but it's amazingly effective.
