Also - SoulDiva & hedgehog:
Not sure what part of the industry you're in (or if there is a better place to post this, someone just let me know) but there's an organization run by the Grammy Foundation that specializes in helping folks in entertainment :
Addiction Recovery Resources | GRAMMY.org
They hold weekly meetings in cities all over the US. They also have specialty meetings at any large music event (Grammys, music festivals, etc.)
Just in case anyone needs it!
