Cola I had great experience with Clear Lungs. At the beginning I did it twice a day 2 caps. I had hardly mucus after but nowI take as needed. I haven’t had any bad experience breathing since. I always have some to make sure I decongestion my lung right away. I stop when my breathing is good no wheezing. I have bronchiectasis and they found a MAC in the la culture after a bronchoscope.I haven’t had any test or other treatment since. It’s been 2 years. I thank God every day. If your symptoms are bad you can follow the directions on the bottle. You must have a good healthy diet no fried food. Once an a while I do but I treat myself with Milk Thistle, Colustrum, and clear lungs when I wheeze a bit because of the mucus forming. I stay away from citrus fruits, all sweet drinks like cola...Etc, citrus juice and dairy products, It isn’t good for acid reflux and gives me mucus when I cheat.i decided not to cheat too often lol ! Hope this help! Do not hesitate if you have any other questions! Nic
