I've done this as well but the flip side for me is that I find myself probably checking various apps (etc) for new content probably more often than I would if I just had notifications on.
So ultimately, I feel like I've replaced an intolerable amount of notifications with an intolerable amount of application switching.
I acknowledge it's a me problem, of course, but it's still a problem. We are way too peppered with bits of "info" from way too many sources.
Give yourself a window to check notifications and doomscroll. It's easier to tell yourself "I can wait another hour until my lunch break when distracting apps are allowed" rather than fighting the urge with no relief in sight.
Personally I have settled on keeping social media and notifications blocked until 2pm. Much easier than wishing and failing to be a productive machine for the entire day.
