I have been doing advair for a while now and have the Disc powder version, don't know if you can get it other ways. Anyway, I notice when I inhale this lots of times it seems the powder just sticks to the back of my mouth or throat. It this normal, I have always wondered how much of the powder is actually making it into my lungs. Anyone else have this problem, know if this is normal, or if I am not inhaling this properly. Thanks.
