I, 35 years old man, quit 117 days (4 days to 4 months) ago after smoking for 18 years. I am still coughing out black tar (phlegm? not sure) 2/3 times a day. It's not everyday but almost with very little gap. I do not have any cough except 2/3 times to throw out tar possibly due to irritation. I am wondering if anybody had such issue before. I googled the symptom but could not confirm how long it stays and how to handle this. I am posting this experience for the record because even if I do not get any answer, at least people will know that such thing can happen and they may not get worried if they experience same. Any help would be highly appreciated. Thanks in advance.
