I started this in July. I am now on Singulair (30 days now) (prescription) and NasaCort
(over the counter), using the saline rinses, and air cleaner in my bedroom. Had my furnace cleaned, my carpets cleaned. As long as I stay away from odors of any kind, aerosols, candles, won't be around cigarettes, I seem to do better. So my suggestion is try to rule out some things. I am considering the allergy shots because I can't avoid smelling grass cutting this summer.
