If your phone has "focus" modes I would highly suggest auto-disabling notifications after a certain hour, when driving, when working, etc. My phone even changes the home screen for me. At night I only have the clock and notes app on it, for example. I personally have ADHD and this phone feature is a lifesaver.
Disabling all notifications during the day was a fantastic life improvement for me. I had a period of time in my job where I struggled to get into the projects and had zero passion for what we are doing so it was easy to get distracted. Throwing myself into my work for bursts at a time with zero distractions actually brought the passion back as I felt more invested.
I have a period of time in the morning when I'm usually catching up on emails, drinking my coffee, browsing HN, etc and a period after dinner but before bed where my notifications are on. Any other time, call me twice and I'll answer.
