I am using vicks inhaler since much time. It is very useful thing. It provides instant relief from closed nose in case of cogh and cold. Using it clears nose and feels me relieved for some time so that I can do any work . At the time of going to bed due to closed nose I face problem in sleeping but using its gives me comfort. I keep vicks inhaler all timewith me. I bought it from any medical shop. Also when I am going somewhere and faces untolerable smell than I use it to avoid that smell. Although this product is very good for me. Thanks.
