Last year around March i got really sick. Coughing up phlegm and mucus was one of my syptoms. Then my sickness slowly went away but the phlegm and mucus never did. Ever since then, to the this day i hauk up loogies all day. Before i got sick last year i never had this unless i was sick and even then it wasn't as bad as it is now. Is this normal? Why won't it go away? And does it have to do with smoking? I've been smoking for 2 years
