The older you get with CF, the more irritable you become from common respiratory irritants, especially so with chemicals (perfume, cleaning chemicals, hairspray, etc etc). The good news is you have something generally new to complain about. The bad news is, you are less for this world. Don't feel bad, I now have more of this problem than I used to as well, especially regarding cig smoke. All of the close CF's I knew that I basically watched decline and die, chemical sensitivity became a much larger issue as they declined.
