Thank you for that link, it was very interesting and informative. I do lots of research and will add this to my list.

I have not taken any meds since my initial diagnosis in 2015. I personally feel doctors over prescribe antibiotics, prednisone and inhalers.

I prefer a more natural approach. I use steam inhalation when cough gets to bad, take probiotic supplements to better my gut flora (increases natural immunity) and drink lots of water. Plus I eat a plant diet with lots of fruits, vegetables and whole grains. Limit sugar, processed foods and absolutely no fast food.
