I am a 45 year old female, I have been on Advair for about 4 years now. I tried to go off of it once because I was having heart palpitations, I had to go back on it because of my asthma, waking up in the morning feeling like I couldn't breath just didn't work for me. I have less heart palpitations and my asthma is in much better control, however (isn't there always a "however"! I have been dieting and exercising like crazy (ok, all my life, but seriously for about 6 months now.) The scale has not moved...and I mean nothing, not a pound! I could not put my finger on it until now...it must be this drug! What else could it be? So now I have to decide if I want to be thinner or breath! Huh....some choice!
