I have found after years of smelling strong chemicals almost everywhere I go and having them linger constantly in my nose even after I've been away from the source, is that the problem was actually in my nose (body). I could smell paint, gas, mold, perfume, sick people, cleaning products, detergent and most any toxic fumes; and once I had an intial exposure, it would cause me to be ultra sensitive and to feel as if I was swimming in a chemical soup odor. Right now I am 100% free of this hyper-sensitivity and my nose is completely clear and fresh and normal in it's smelling sense. This healing occurred through ridding my body of systemic Candida, especially the yeasts that were living in my nasal and sinus passageways. You will be amazed once you start to eliminate this fungus, how much toxic yeasts have been lodged in your body affecting its basic functions, i.e, sense of smell. I explain how I went about cleansing my body of these pathogens on my blog at [link to heallovenow.blogspot.com] Bless you and don't give up hope. I think I had it worse than most and am totally free of it now!
