I had EIA as. Kid, but grew out of it in my mid teens. It then returned a couple of years ago in my late 30's. Only really on harder efforts and also coincident with pollen allergies (new for me). Now I use Advair and an antihistamine in the spring when my allergies flair up. I rarely feel as though I have asthma - it doesn't impinge on any of my activities at this time, in recreational riding or in races.
