I have been on advair for just over 2 months, i too have had all the symptoms that all of you have experianced , and stopped taking the advair as well. My symptoms are severe muscle weakness, pneumonia, thrush, major phlem, hoarness, neck pain, mood swings, aggression, excitability, weight gain (25lbs. in 2 months), i was givin advair for COPD, and i told my dr. of my change in symptoms, and they said it could not possibally be the advair millions of people are taking it . So i took it upon myself to stop taking it its only been 2 days without it, and i have yet to start feeling better.
