@mrf5629 Beth, yes, I take it in capsule form and bought it a vitamin shoppe right near my doctor's office. I, too, have a had a terrible cough for two and a half years and I, also, decided to take the problem into my own hands because NEITHER of the two pulmonologists seemed to care about my cough at all. I got it with the 2018 flu that almost killed me. So I decided to do what Daniel Pecaut did in his book, Beating Bronchiectasis, gathered up my own team and tried to do most of the things that he did in his book but I didn't do all of them. I did go to an acupuncturist for a year to see if that would help with the cough. It didn't really but it might have helped in other ways. I then found a functional medicine doctor which I now wish I had done years ago. They're doctors, generally, but have added integrative, and alternative solutions to problems. They look at the WHOLE patient not just the symptoms. Anyway, went to this wonderful doctor and he started with allergies and it turns out I'm allergic to everything....trees, grasses and weeds. He was right in that he thought this might be an exacerbation of sorts to the cough. So I've been giving myself allergy shots for a year now, as well as exercise five days a week for at least 30 minutes and am taking other supplements, too. And at my last CT scan which was a month ago (the first one in two years), the nurse practitioner looked at it (because I hardly ever see the real doctor who's the specialist for bronchiectasis) and said "there's no progression"! and then she said "whatever you're doing, keep doing it." So, not to knock the western medicine doctors but the past two years I've have been totally on my own trying to figure out this lung disease and coughing. I didn't succeed like Daniel Pecaut (yet) but I've had no progression and I consider that a win! I also do the saline solution just about everyday (that I learned from this forum. My local pulmonologist didn't really prescribe it but I made him find it and give me a prescription. And then I nebulize with glutathione almost every day (it's not cheap). My pulmonologist would not help me with that either. When I asked him about he kind of rolled his eyes and said "oh that's the stuff you get at the health food store". Well glutathione happens to be the single most important antioxidant in the human body says my functional medicine doctor and he gives me the vial of glutathione that I mix with my saline solution. So I can't pinpoint what exactly gave me 'no progression' but I think it's probably a combination of a lot of things just like Daniel Pecaut. And Daniel Pecaut had a Mayo doctor who stuck with him through his year of non-western medicine journey which I think is so admirable. And he looked at Picauts CT scan at the end of his year and gave him the results. Complete reversal. So I might not be there yet but I'm sure as hell working on it. Sorry to ramble but I wanted to let you know there's hope sometimes in all of this mess but you really and truly do have to be your own advocate. There is no question. Western medicine is a great thing but it's not the be all and end all. I think you have to mix in alternative and integrative therapies. And the cough is still not completely gone but I'm not giving up. One day I will get rid of it. Nan
