I am struggling with quitting smoking. I am pregnant and after I quit I noticed that probably due to anxiety sometimes I have shortness of breath. But that has gotten better slowly with time. Sometimes I wheeze once or twice at night but if I cough it stops. Usually when I am laying down. I have been coughing up yucky flegm also. So I bought myself a humidifier to help me clean out. Does anyone who also quit have these problems? Please respond asap because I hope I am not the only one. Thanx a lot
