What you describe sounds like chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis
, due to cigarette smoking. The coughing and wheezing may persist for
months or even years. But, your decision to quit smoking is extremely important. We would urge you to stick with it, no matter what.
In the meantime, you should be treated with respiratory medicines for COPD/asthma, which are capable of providing good relief of the wheezing and difficulty breathing.
