Just caught up with this after seeing Dee's post in the Sober Rock Stars thread. There is such a strong link between bands and drinking, it's great to see so many people breaking it.
I've "come out" as sober to my own band, which surprised them, but no bad reactions. Sadly, our keys player appears to be sinking fast in his alcoholism, and hasn't yet accepted he needs help. I'm trying to figure out what I can do, but we don't have a friendship outside the band and only ever really talk about music, so tricky to know how to even bring it up without being told where to go.
