I was diagnosed in Nov 2020. I too have the cough - I will not allow it to stop me from living. I have oxygen avail but as yet not using. I check my 02 levels frequently. Cough comes-goes on its own. Strange but what seems to help me are Mentos, when I am out and about. Guess its the mint, but calms cough to some extent. Was prescribed Benzonatate pills for cough, doesn’t seem to help any.
I believe moving helps loosen up the mucus to help get it up. Yes, it is a pain and disturbing to others. I have snuck out of venues to go out and have a good cough, then go back. Gotta live/love the life you have remaining - try not to let it consume you. I too was a caregiver to my husband - bless you and take care of yourself also, so spouse does not worry about you also.
