I'm 28 and have had asthma for a long time but a recent bout with broncitis has me currently using my inhaler quite often and it dosn't work as well as it used to. My doctor is thinking about getting me a portable nebulizer if this doesn't improve, and of course, in 3 weeks I will be on a plane to WDW so what happnes if I need a treatment on the plane and have to use the nebulizer? Is this allowed, or will I have to rely on my less helpful albuterol inhaler until we land?
