I quit cold turkey on January 17, 2015 after 55 years of smoking. Now, 6 months later I think that I wheeze more now than when smoking. Also, I find I have to cough out heavy mucus about 10 times a day. Mucus that seems to be in the high part of my chest and difficult to dislodge. Will the wheezing and coughing gradually abate, or, am I stuck with it?
