I'd try to get the bouncer to open up a back door so there is some cross-ventilation going on. But then again, here in State College, PA, the only time I go to a pub is on St. Patrick's Day, and that's to the Phyrst. It's usually a trip, and a good way to find $20 bills on the floor, dropped by a drunken sot.

Anywho, I just hit the old nebulizer or inhaler before going in, and have the lil' squirt around at all times. I play the recorder, so it's a bit different. The breathing problem is still there, but I can still play the next day to open up my lungs. I've notice that whenever I play more than 15 minutes, my peak flow is over 500 lpm.

Maybe playing a woodwind is the answer.
