another asthma sufferer here. I can't use any of the steriodal inhalers, they roughen my vocal chords to the point I lose my voice and as a singer, that's bad! I do take Singulair and Claritin and I have albuterol for the really bad days. Most of the time if the climb gets so bad I can't breathe - I just stop and catch my breath. Or, I just turn around and have a wicked awesome descent and try the hill another day. I figure riding a bike is just about the best thing in the world for my lungs - ok...that and living above 5000 feet!
