I took Advair about for 2 years. Hoping, that it would help to breath easier. I did not feel significant changes in my breathing. But I started coughing.Bedly. At work my collegues kept bigger distance from me, they did not want to be infected from me. They did not know, it was not contagious. I have sinus infection, dry mouth, respiratory problems, since I was using Advair. Now, on my own, I stopped to take it. I had enough. Taking medicines for the side effect of the medicines. Maybe I never had asthma, only the doctors irresponsible decisions made me belive, I had it. I already suffered from the side effects of prednison. (joint surgery) The doctors used to give to me, in large dose. Now, after several years, I was told, maybe I never had asthma. How can we trust doctors?
