Cook dinner, eat it away from your computer, and wash the dishes. (Or go out, or do takeout.) When you're done, do something that interests you. TV, games, hobbies, side-business, open-source project, ect.
If you're still ultra-focused on work, do a skunk project. (IE, the "work" things you want to do but your boss won't let you do.)
(And, maybe this is unrelated, but if you're on meds like Straterra or Adderal, this is something you should talk about with your 'shrink... Or maybe just find a different doctor if they've had you "trying this and that.")
