Wow, deea,
I haven't gigged regularly for close to 20 years, but the worst night was never like what you describe. I'd quit if it was. I'd hate even going if it was like that. I wouldn't want to play at all if it was that terrible.
I still do an occasional thing with some friends or family, and I still love it.
Even way back when, on the occasional nights a heckler was giving us a hard time, or when I played one weekend with influenza, as bad as that was, what you describe sounds horrible. I can't imagine sitting, pissed off, thinking about not smoking or drinking when waiting to start playing. We were always too pumped just waiting to get out there and wail. Maybe it's different where you live.
