Sorry for your hardship, BOTL....
But I am inclined to agree with some of the later posts here:
I am a military doc in the Canadian Forces, and "reactive airway disease" doesn't scare me much. But, it could be bad or nothing at all. If someone was throwing ideas of epiglotal involvement at you, they might have been oversimplifying in a way that left false beliefs behind.
I personally have "reactive airway" tendencies, which have not gotten any worse with taking on cigar smoking (1 a week). With that I have been able to pare down my 1.5mile run from 9 min 18 seconds 6 weeks ago to 8 min 52 seconds.
While that is my story, it may not be yours.....but it may not require as harsh a decision as selling your collection (regardless of how much I want to take it and the humidor off your hands

)
Give me a PM, we should talk....bring your lab results (I presume you might have some number available from a PFT - pulmonary function test)....
We can discuss it in a framework of doing what is right for you based on best evidence (if quitting is the best option I will tell you that, but if calculated indulgence can happen without likely increasing risks I will tell you that too).
