I've recently adopted the grey scale trick -- set your phone to grey scale display mode. It works pretty well! Of course, I can always disable it if severely tempted, but it creates another hoop to jump through. I also have one of the phone safes, which I use sporadically. Ironically, having an Apple watch makes the phone safe more effective, because I can lock up the phone but still answer critical calls if necessary.
Weird that in the 23rd century, a lot of us are replaying Oddyseus, collectively tying ourselves to the mast.
