I've been Social Sober for 20 days now. I didn't delete any content from FB, since I had been using a fake name on there for 5 years. I just deactivated the account and haven't logged back in since.
I honestly haven't noticed much of a difference in my life. I still work all day, come home and watch Netflix or play my Switch.
It's ok to not "know" what's happening. Just do it!
