Edit: For anyone who wants it, here are some prompts for brainstorming things to try giving up (set a 5-minute timer for the brainstorm):
What takes up too much of my time?
What takes up too much of my attention?
What in my life is most out to get me?
What superstimuli am I most attracted to?
What in my life feels the most like pica?
And also for anyone who wants it, here are some concrete suggestions for things to give up, in no particular order:
Facebook, Reddit, etc.
