I have Bronchiectasis and of course cough, sometimes a little, sometimes a lot. One of my "types" of cough starts with a sharp tickle in my throat and I know I am in for a long bout of coughing when I feel it. I have tried everything, water, cough drops, honey, lemon, ginger, every herb under the sun and more.
I know that there are times when I need to cough to clear my chest. However, there are times when I don't want to cough, e.g., in the middle of the night when I am asleep, when I am out to dinner, when on a bus, etc., and I have solved the problem. I now use sore throat tablets that anaesthetise my throat, Chloralieve, boom boom, tickle killed stone dead within 5 minutes. what a relief. Sleep resumed, disapproving stares stop and sanity restored.
Hope this helps someone.
