I am allergic to cats, dust mites, ragweed and other pollend, seemingly all tree nuts (sigh), new ones may be fish and shrimp, and because my allergy to the omnipresent dustmites is so strong, basically my immune system is always on high alert, so anything perfumed, ammonia, many cleaning products (409 is safe, most others make me wheeze for hours), smoke of any kind, and many, many more. More all the time, lately grrrrrr including some unknowns, so I am getting my allergies tested again in January. Oh goody.
