I did it for 3 months. I really enjoyed my time doing it and learned a lot about my usage. It was a cheap $50 experiment. After I went back to my smartphone, I uninstalled ALL social media apps. Turned off ALL notifications but left calls and messages as an exception. My smartphone is now essentially a feature phone. It's not 100% the same since the big screen does lure you in to use it but my usage is still way down and because I don't have any social media there's no reason for me to be on my phone around other people. I wholeheartedly recommend trying it for those curious.
