Thanks for your comments about cold air. You are so right. I live in Northern California and the air is cool now so I am house bound. Any air below 70 degrees seems to tighten my bronchial tubes and so are thinking seriously about moving to Arizona where it is warmer year round. Also, I took your advice and tried Fisherman's Friends cough lozenges. I don't have a coughing problem but do get tickling and irritation in my throat with asthma. Perhaps FF cough lozenges could help with reducing inflammation as well. I am giving them a try! Thank you.
