FWIW, I found that losing that tended to remove low-productivity time - I do work at my desk and call it a day, whereas it was a little too easy to be hunched on the couch surfing HN. If I really want to do something, walking over to the desktop only takes a few seconds.
Granted, becoming a parent also meant that things like watching a movie are “haha, I’m going to sleep” now, too.
