@bechtlerd, welcome to Connect. I am glad your research brought you to this forum. Our mission is to help every member have a better quality of life as well as a place to get feedback from other members who share our experiences. Somewhere along this journey, I had a similar cough. My companion and life partner was very worried that I was developing something contagious. To learn more about Neurogenic cough reflex, I researched like you and on a public med site found the recommendation for amitriptyline and gabapentin.

So....it is not working as well for you because of side effects. What are they? Is there any way to get around them? The reason I asked is that if you choose CBD without the entourage effect of some THC, you may not have the best response. CBD can be calming especially if you use a high-quality medical cannabis source. If you are doing research you might try the Leafy site. I find it the most reliable at this juncture. If you must omit the THC then try the Papa and Barkley all CBD site. I have been using their products for five or six years and they are consistently
reliable. You can also ask questions and get answers promptly. Perhaps there is a ratio, e.g. 30:1 CBD/THC that will work without getting noticed. I truly don't know.

What I do know is that you cannot trust the consistency of unregulated products that are sold on the street. Let me know if I can help in any way.......I can cheer well.

May you be free of suffering and the causes of suffering.
Chris
