This is definitely an option; we as a society did it for centuries.

It will impact your social life, but you can mitigate that if you put in the effort.

The worst for me when I don’t have my phone while driving. It’s an odd anxiety.

In these discussion threads I always see people mixing call/gps functionality (which is genuinely useful, especially in case of an emergency, and not addictive) with social media. You can have one without having the other. Instagram didn't come with your phone, you installed it. So, don't.

There's a lot of people who show up in these threads whose only coping strategy is to go cold turkey. Maybe that's good advice, but it's not the only advice. There's no reason you can't carry a smartphone in your pocket without it becoming a pacifier.

Devil's advocate here: addiction is tricky. There's no reason you can't carry around a pack of cigarettes and not smoke them, either, but in practice that strategy would not work for many smokers. Cold turkey isn't the magic bullet, but try whatever you suspect might work.
