I had chronic cough, kept being told allergies, post nasal drip, had ct scan of sinus's..nothing, my gp wanted me to go to pilmonary, and I decided to seek gastro insteas..,Sure enough LPR, and started 1 aciphex a day, helped, but still alot of coughing, convinced Dr to see if 2 a day would do better, sure enough, my life is back to mostly normal..I still cough, but nothing like before, if I eat especially chocolate, I cough right away.
