asthma
"I have had asthma since infancy.  (I am now 81!)  I have probably used all the common medications - i.e. albuterol, singulair, etc., etc. in my lifetime.  Dulera allows me the luxury of one puff at night, and a good night's sleep.  I am otherwise very healthy having long ago given up the things that are bad for health, like smoking, eating sweets, alcohol, and I have a wonderful life!  So part of it is the medication, and part of it is up to me - my lifestyle."
