I have COPD, so decided to try it last year. After 6 months, I didnāt think it was doing anything, because of course, I have a inhaler that I use on a daily basis. A few months after I stopped, I started wheezing and finding it hard to breath. I decided to start taking Better Lungs again, and am now breathing much better!! Of course, the first couple weeks of taking, I coughed up a lot of crap, but now, Iām almost as good as new!! I think Iāll continue with Better Lungs!
