I have been on Advair for three months now after the Albuterol inhaler didn't seem to be working. Since then, I have noticed I am gaining weight. I have an active job and my diet is healthy (vegetarian). In six years my weight has hardly fluctuated. Aside from weight gain, the most disturbing side effect has by insomnia. I am simply not tired and when I do sleep, not matter for how long, I always feel tired. I did a search when it dawned on me that the only thing I have changed in the last three months has been the Advair.
