Thank you for responding!  I have seen a pulmonologist-diagnosed with symptoms and a positive methacholine challenge test.  I am on Symbicort, albuterol, atrovent and singulair.  I have seen some improvement since I began the drug therapy about a month ago.  However, the poor endurance, weakness and shortness of breath (by the way I did see a cardiologist and my heart is perfect!) continue.  The wheezing remains but has diminished somewhat.  I had a mycoplasma pneumonia in March of this year.  Since then I haven't been the same.  Actually, since I had my baby 4 years ago I have been worn out have tired easily.  I have never been a sickly person.  This has all been a bit depressing!  I feel for people who have serious, chronic illnesses.  Thanks again for responding.  If you or anyone else reading this has any advice on dealing with asthma

that would be great!
