I am not cetain Advair is the cause of this but about year or so ...

I am not cetain Advair is the cause of this but about year or so ago I started experiencing fainting feelings and almost passed a couple of times. The doctoer ran tests and everything seemed normal. One day I was paying attention to the side effects of Advair via an ad on tv and was stunned. I stopped Advair a couple of months ago and have not had these "weak spells". Now it may be a coincidence but I won't be using it anymore so time will tell. Has anyone else experienced feelings like this?
