Twice in my life I have had a persistent cough. My doctor believed it
is asthma and I agree.  I really have never had weezing or shortness of
breath, but this time I can tell I do slightly on occasion.  Last time
he gave me 2 inhalers. I kind of used them and the cough went away.
Now, 2 years later, the persistent cough is back.

My question is is there anything I can do other than go to the Dr. and
get 2 inhalers?  I mean, it seems to me that if this is only occuring
every 2 years,  it will go away by itself and I need temporary relief.
My other thought was it could be something in my house/surroundings
stimulating it.  The first time it happened in Feb (in Chicago) and
this time it is summer (in Chicago), so season doesn't seem to matter.
