I was sick like a month ago w/ the flu. When the flu was over, I was still left with a light cough. The cough went away but the phlegm continue to persist up until now. It's not as bad as before but I still find myself coughing every morning to get rid of the phlegm stuck in my throat. During the day I would also have problems trying to talk in a loud voice because of the phlegm stuck in my throat. Is there anyway to remedy this?
