I have a dry hacking cough that is at sometimes severe, I have noticed that after I eat I have episodes of severe coughing almost to the point of vomiting. I have had inhalers, and about 8 cough medicines to severe strength and they do not have any effect. I have had a chest xray and all is clear. This is driving me and everybody around me crazy. I take priloec daily and have not had a problem until a few months ago when this started. Any thoughts Bob
