Attempting to manage cough, chest tightness. Raised in home where I was exposed to second-hand smoke for 18 years. never smoked. Don't have GERD, asthma, or heart issues. Currently on guaifensin, and Qvar. At times the cough is fine and other times it appears to get worse. (evenings and damp cold waether) What works best for cough and chest congestion? Am 63 years old and in good health otherwise. I'm trying to learn and live with this chronic issue in the best ways possible. Diagnose in January. Allergic to albuterol.
