I smiled at the FB mention. A beast for me too, at one point. I quit it for awhile, even before becoming sober, and now consciously use it sparingly, only positively, and post minimal stuff! SO much better, and still lets me get its best use- staying in touch with people near and far that I truly care about.
Have a good day 4! And yeah, you'll keep sleeping better particularly with the subconscious knowledge you won't wake up to regrettable junk.
