Not sure whether I developed a tolerance or the inflamation has gotten worse. I think the latter unfortunately. I have been tested recently but under the influence of the Pulmicort which had been working. I'll discuss all of these things with the doctor. I also remember at one point a few years back before I increased the dose where a few times at night I felt I couldn't take a deep breath. One of those cleansing breaths. Of course once I increased the dosage I didn't have that problem either. Or it just could of been my imagination. I'm tempted to go either get a stress test with a mask and/or go off the medication entirely for a short while to see where I am really at. All these things I will discuss with the doctor including the Advair. I had bronchitis a few months ago and for two weeks I was on Advair to help clear it up. I stopped the Pulmicort for those two weeks. I seemed to work well with it.
