Hi Lena,
While this is not CS related - however, my chiropractor saved me from
misery when I had intense cough attacks during nights - so bad that I could
not sleep for 3 days --- skeptical, I tried the homeopathic based on making
sure I found the right cough description that matched mine - and to my
surprise, it worked. I can't say it will work for everyone, but if one has
tried A to Z --- one more couldn't hurt to try.

Here is a website that shows a nice chart of different kinds of cough:

Be well!
