Absolutely STELLAR! I just downloaded this and read a few chapters - and wow, what a difference it would make if every professional treating asthma had access.
I heartily recommend anyone struggling with asthma control download and read the relevant parts of this guide.
Based on what I just finished reading, I am going to ask my pulmonologist whether we can do a trial of stopping the Singulair (Montelukast) I have been using for many years, as long-term use issues begin to emerge.
