I'm interested in some feedback on my EIA experience.  I'm a long
distance bicyclist who lives in the Chicago suburbs.  I begin riding
outdoors in March and ride through October. When I begin riding in
March the temperatures are often below 40 degrees and plants are still
dormant.  During this period, I have no symptoms even though I may do
difficult 50-80 mile rides.  Beginning in mid-April through October, I
ride 100 miles every Saturday.

As the temperature and humidity rise, and plants begin to blossom then
my EIA symptoms begin to appear.  They are most acute when it's warm,
humid and a lot of pollen is in the air (spring and early fall).
During late winter, early spring, summer, and late fall, I don't have
any symptoms.  They often don't start until I've been riding two or
three hours and get progressively worse through the end of my ride (5 -
6 hours).  Note: I do not have any symptoms when the weather is cold
and dry as is often noted with EIA.

During my EIA periods, I have labored breathing and difficulty
speaking, but can still ride at a good clip (16-18 mph).  The more
acute symptoms of being so short of breath that I can't speak typically
end within an hour or two of my ride.  General shortness of breath can
last up to a day or two before I fully recover to normal.

I've tried Albuteral, Serevent, and Inhaled corticosteroids with little
success.  I was thinking about trying Cromolyn as the facts and my
research indicate that my asthma may be alergy induced.

Just wondering if anyone has experienced a similar case and what my
have proven successful.

Thank You
