I dunno. My lungs were already f'ed up from having asthma. I'm not sure that's the problem now because when I try my inhaler after being active, it makes my cough 50 times worse.
Ugh, the pits. Have you tried zinc or coldeze? For some reason, it seems like coughs go away sooner when I use those lozenges.
but .... of course, if it is in your chest, probably not much help.
