I am having a lot of problems with thick mucus that I don't have the lung strength to cough out. I have tried many things to help thin the mucus... drinking warm tea instead of coffee, using a whole house cold mist humidifier, using distilled water on my oxygen concentrator for moisture, and Mucinex DM. Nothing I have tried is working . Are there any natural vitamins or supplements that help with lung congestion ? I had a very bad experience with Mucinex ( actually made my mucus worse and I almost drowned on all the mucus), so I would like to hear from some people with stage 4 COPD who have tried different supplements, as I am very fearful of just trying anything π Thanks everyone π
