I am 19 years old and started Advair only 2 weeks ago, and already I'm feeling the symptoms other posters have mentioned. My back pain is unbearable, I can't even get comfortable long enough to fall asleep. I'm having extreme irratibility and mood swings. I have such muscle weakness that I can barely open a jar of peanut butter. On top of all of this, Advair is just barely doing anything to aid with my asthma symptoms. The side effects of this medication are not worth any of the help it provides.
