I have had a terrible cough for going on two years. I’ve seen several doctors and been given different types of medication. It seemed to me that I would be saddled with this cough for the rest of my life. My husband bought an Alen Breathesmart 75i. Within a few days, I could tell a difference and within a month I scarcely cough at all. It has made a tremendous difference in the quality of my life.
