question: Hi.  Im a 49 year old female smoker (started smoking when I was 8).  I have COPD and asthma.  I have been battling my cough for the past few days and its is getting worse.  Im out of town so seeing my primary or pulmonary docs isnt possible at the moment.  The cough is hollow and seems settled in the chest, but the smell and taste are terrible.  Any suggestions?
