First, I must say that ADVAIR always did exactly what it it supposed to for my astma. Within two doses of the medicine it has always soothed my lungs and helped me breathe.
But I have always gained weight every time I am on it for more than a month, so I wait until my asthma is pretty bad (usually in winter time or while allergies are bad). I use it intermittently for a month at a time and that helps keep my weight normal. If you suffer from a lot of candida, like I do, you should also be careful and stay away from eating a lot of sugar.
My doctor thinks I am crazy because I don't want to be on ADVAIR all year long, but it seems to help the way I do it, and I think that is the most important thing.
