Even though it works amazingly to control my asthma I have suffered from insomnia, exhaustion, acne, mood swings,and a significant weight gain. I work out like a crazy person and live on lettuce and am still gaining. I was never told by my Dr of these side effects. I am at least relieved to know that I am not alone. I have been off Advair for only a couple days now and already feel a shift for the better in my health.
