I'm in a same boat as you. Between work, family, and house projects, I barely have any time to do anything I want to. So when I do get such time, I blow it on gaming as a form of relaxation.

One thing that really helped me was during work hours, if I have downtime, I'll spend it on either searching for new projects to do or learn new things. Once I'm home, my emails stop syncing and I concentrate more on home and family related activities.
