Can't recommend this highly enough! The only calls and texts that break through are from contacts; the only notifications that require my attention are from apps I explicitly allowed to do so.
From time to time I expect calls from unknown numbers (e.g. recruiters) and have to disable DnD mode - it's just unbearable how much crap starts demanding my attention!
Every time I visit my parents and observe their phones, I can't believe how anyone can live with it. All the notifications lighting up your phone every minute, all the dinging and buzzing for your attention. 7 unread messages! 8! Now 10!! Ding ding ding! New reply on your Facebook message! Ding ding! It's like living on the Las Vegas strip. I'd be a basket case if I had to go a day with all those demanding interruptions.
I start going crazy visiting family too. Beeps and boops everywhere: phone notifications and ringing, the washer and dryer play electronic tunes, every external door makes the alarm system make an alert sound when it opens. Kitchen timers and microwaves. A driveway sensor goes off when anything arrives (plus false alarms). Somewhat related: the tv always on, generally including commercials.
Plus my own stuff: the car’s beeps from lock/unlock, opening the door with keys or not putting on the seatbelt fast enough. My phone if I’m on call. My work computer’s email and chat.
