I have exercise-induced asthma, too. I still breathe hard on hills, but the difference is amazing. I had thought I was just out of shape, so the first time I went for a ride after using my inhaler, I was shocked. The only thing I could think was, "this must be what it's like for everyone else!"

So if trying to control your breathing doesn't work, and you're actually having difficult breathing, go see your doctor. It never occured to me that I might have asthma, and I definitely struggled with it for far longer than I should have.
