I already know I'm lucky/blessed to be in the band situation I am; every time I see one of these topics, it serves as a great reminder. We're just a 3 piece, so less chance for drama, but we complement each other well musically, and we all get along very well. No backbiting, we're all on the same page musically and in terms of priorities. We all enjoy a few (literally) beverages during practice, and maybe one or two during a gig. No issues with too much drinking, or substances.
