A thing that helped me was to break my day in half (well, two distinct segments). I go to my day job, then I go exercise (I haven't done this daily like I used to but still 2-3 times a week). I don't wait 2 hours to exercise after work. I go from work
to exercise. Either a run at a trail near the office, or the gym near my home (there's about a 30 minute break between when I get home and when the class I attend starts).
After the runs, in particular, I feel both exhausted and refreshed. After about an hour, a shower, and some food I feel capable of focusing again. The TV is still present, and I may turn it on and watch something. But it's not as vexing an addiction as it was prior to developing this routine.
The work of my day is too draining (mentally usually, emotionally sometimes) to be able to transition easily to more work, even if it's work that is more emotionally satisfying. This division gives my mind a clearing period (I've said before in other posts, running for me is meditative, so is the very exhausting conditioning class I attend, once I get into the movement).
