I had problems with chronic cough. It started with a chronic cough that lasted over 3 months. Afterward, I became sensitive to having cough. What helped me, is whenever a feel cold, I dress warmly. I do not mind about other people. I putted on my winter coat even in September before everybody else. I had to work at a place with air conditioning. What I did, I kept warm close at my work, even long underwear. Even in the summer time, at work, I would put on heavy clothing. If not, I would catch a could. People would tell me: Why do you dress so warmly? I said: I have to. This helped me very much. Now, I am doing better, even do, I still have to be careful. I hope this can help you. God bless you.
