Hi bassman, Thanks for reaching out to us in our forums. We are sorry to hear about your acid reflux. While I hope the community can provide you with some of their personal experiences and support here is an article that may be helpful: https://copd.net/answers/expert-answers-vocal
Addiitonally, you may want to reach out to our Facebook community who may be able to provide you with some feedback.
Lastly, since we don't have a direct article relating to acid reflux and COPD, I will bring this back to our team of writers and see if anyone has experienced this so we can get an article on our site.
We hope you get some relief soon and thanks so much for being part of our community.
Best,
Lauren (COPD.net Team)
