Hi , I’m new to this site ,,, but yes is the answer , I was diagnosed with asthma at age 46 , then in 2004 I was told I also had bronchiectasis ,and then Copd , , I’ve been prescribed carbocisteine to help with chest clearance,,but I’m afraid I won’t be taking them anymore as yes they help ,,,,but I cough that much during clearance that my throat closes up ,,,and I get extremely breathless,
