I just saw your 2019 post. Have to tell you, I had started NAC after seeing an article by mercola.com (Dr. Mercola). Three years ago I was hospitalized with bronchiectasis with atelectasis and looked like a fish out of water as I could barerly get air in. I'm also a cancer patient and have 6-month PET scans. On several scans there were nodes in my lung and doctors were concerned about metastases to lungs. Well, I started the NAC inbetween PET scans and my miracle came when those nodes almost completely went away! I kept telling the oncologist that I felt the nodes were due to bronchiectas and more atelectasis after having the flu quite bad last March (which I believe was Covid as my lungs went downhill fast). I not only can get whole breaths of air now .... I have not even had to use my nebulizer treatments or The Vest lung machine thumper since last November. I'm sticking with my NAC supplements, but will look into the Jarrow time-release one.
