weight gain,extreme tiredness,insommia,high blood pressure and constantly thirsty and always hungry. when i first took advair ..my dr prescriped it without doing any breathing tests just heard me cough. asked if i had asthma as a kid. said no just bronchitis( sorry typo queen here).i had pnuemonia twice. anyway i quit the advair after seeing the side effects but still can't lose the weight. how long does that stuff stay in your system? will i ever be able to walk distances again without having to stop and lean against something ? any input would be helpful..thanks
