Dear V. --
Yes, we have many things here in Arizona that get into our nasal passages that can cause irritations and that is why I am going to suggest to you that you clean-up your environment for everything else, so that this irrittion is lessened. It is not just the environment that is doing it. It is all of the household cleansers, the laundry products, the kind of hairspray and shampoo, the deodorant, even the pre-natal vitamins that you are probably now taking.
There is a company that will make a world of difference for you. You can have an absolutely non-toxic, hypo-allergenic and totally dust-mite free environment in your home and will not be breathing in all of these nasties and then can put something un-harmful to you or your baby at the end of your nostril when you go out -- no one will see it -- and you will not breathe in the allergens from the outside into your system either.
Call me or email me if your are interested. By the way, I do not sell these products. My local number is ###-###-#### and my email is ____@____.com M.
