I am a 27 year old female that was diagnosed with asthma in March of 2004. When I was diagnosed, I weighed 152. I current weigh 165. My appetite has changed completely in the past 2 years. I have very little taste for meat (which I used to love), I crave any type of starch and carbohydrate (which I used to enjoy, but not over-indulge in), and I struggle with depression. Plus, since I started taking Advair, I am always tired and just want to rest when I get home from work. BUT, I can breathe much better than before. The one thing that I've wondering since I began taking Advair is, is it making my asthma worse? I now depend on Advair to breath, and if I don't take it I am a mess. I don't know what to do.
