I have a lot of trouble with \"public\" air, perfume, cigarette smoke, fire places etc. you get the picture. When I take clients to the hospital for treatment we walk past a sign that reads \"if you have a cough or cold please wear a mask...\". I have a lot of trouble not coughing in public so as I enter the hospital zone packed with people of various smells the coughing starts even though I do not have a cold. I often see people giving me the look and I feel terrible but really don\'t want to wear a mask, I will still cough and the mask does not help me make personal contact with a terrified client. They need to see my smile but not hear my cough. This product works better than the gum I used to chew or the name brand cough drops I used to live on. It also seems to keep the sneezing and watery eyes at bay. Please make them more available in my area, they are hard to find.
