FB, many thanks for the reply. I have become careful about 'warming down' after rides, but the hacking still kicks in about 10 to 20 minutes after the ride. I'll try warming down a bit longer to see if it helps...
Your comments about allergens at home don't apply to my situation, as I usually drive to the start of a ride - and there are many different start locations, all over the county.
However a dose of albuterol 5 to 10 minutes from the end of the ride is a "blinding flash of the obvious", yet I hadn't thought of it. I always ride with an inhaler, and will definitely try that. Thanks for the idea.
The patterns that cause the attacks are pretty similar to many others in this thread: Cold, dry weather is worst, whereas I can often ride in warm humid weather and - as much as I
hate the clammy heat - there's often no after effect at all. Maybe my answer is to move to Florida. (Now - I need my pulmonologist to convince my wife that I need to move for health reasons.
)
I've tried the daily low dose inhaled steroid (Advair) - and I'm not convinced that it helps. I Googled "beta agonist inhaler" - and I think Albuterol is one of them..?
I think your move to Phoenix is the answer!
