What Does Everyone Do For Excess Mucus/Phlegm?

Hi everyone, I just rejoined the sub after needing some mental health time. As you all know, this is a monster disease.

A little bit of background: I have a private ALS patient in her 50's who has been having a really rough time with excess mucus. She's starting to have choking fits and is increasingly feeling like she can't breathe. She's somewhat advanced, diagnosis was 3 years ago, has a mic-key g-tube, but she can still assist when standing so she has a lot of strength in her core (We have to hold her up still). She's very much into the natural stuff and follows the Healing ALS group, which I'm not very fond of because they suggest things like using a nebulizer with iodine or hydrogen peroxide, and from everything I read, that's not very safe. (To be clear, she is not doing this). I think she may be open to anything at this point, including prescription medications. I also think she may be vulnerable to bad or unsafe advice due to desperately wanting to relieve the phlegm. Right now, she uses some homeopathic salt concoction that's supposed to thin mucus. It doesn't appear to work, from what I can see. She also has a cough assist but she never wants to use it when I offer. This situation is getting worse so I wanted to come here and ask.

So my question is basically the title. What does everyone do for their excess mucus? What works for you, and what doesn't?

Thanks so much in advance. I really appreciate any input. 🫂❤️
