I had the same problem when I worked. How about your lunch hour? I made a quilt as you go and a Crazy quilt by making the blocks on my lunch hour. It only took me 15 min. to eat; 45 min. to go spend $$$ or relax and quilt.
Another idea; sew while watching tv, if your machine is in the tv room. I have one there and one in the sewing room. It is relaxing to hand sew while watching tv.
Those are ideas that worked for me! Good luck!
