It's been a while since I looked at this website, mostly because I have pretty much got past most of the issues however, I have a stubborn cough that I just cannot shake and have been wondering if this could be related to cpap use. I came here hoping to find some discussion since this seems like it could be something others have had to deal with. There is NO way to search this by item which in my opinion renders this forum useless. So disappointed as was hoping to learn something.
