But I also agree with parent OPs sentiment - going offline, putting your phone away really connects you back to real world and family. This has been studied ad nauseam. Same as food, substance or any indulgent abuse - it's up to you to control yourself.
Why do you assume that OP's employed? And if they are, why do you assume that they can afford to just walk away?
For the second, I get it. Not everyone can. I shouldn't have when I did, but it worked out okay for me after a few months of pain. And I'd do it again in a heartbeat. We had to downsize our lives and I switched to a field I never thought I'd work in. Turns out I love it, and have way more time for my family, even if we can't do massive vacations now.
