Thank you for sharing. All I can say is that for me 12 years sober, that feeling comes and goes. There is nothing wrong with seeking healthy adventure. This Burning Man sounds cool. What I do want to say is that after 12 years I was really not in the middle of AA but on the outskirts for a few years. For me the empty feeling and need for adventure turned unhealthy. What I am finding is that the more I delve into my program and get to as many meetings as possible, arrive early, stay after, talk, share, reach out to new comers, really listen and try to heed advice...well the emptiness is relieved temporarily. It is a daily reprieve only. I have to take action the next day. This is just my experience lately.
