I just tried the FB Purity and put in key words of things I don't want to see including, alcohol-moderation-wine-recovery programs in that section. Interested to see how it changes the stuff I get in everything I chose to hide.
Side note back to main question/OP - I took a break from FB and am now on in recovery. I don't have people who aren't generally positive, and people I actually know, and flat out ignore the crap. I manage a recovery group page and post often there and on my page about my recovery because I am now "out" in all circles, so FB is still very relevant for me.
