I forgot to mention that at the time I began taking it, I was not coughing but having had MAC and bronchiectasis and numerous bouts of pseudemonas, my breathing was impacted. I believe it takes time for it to have an impact but it is not anything you notice right away. I feel it is mostly a "maintenance" thing for me. Perhaps begin with one a day, then work up to two a day after a month or so while you body gets used to it. But if the Jarro is causing the flushing, it wouldn't hurt to find another brand. Pamela
