This summer I have found something that has helped me feel better> It hasn't cured my asthma, nor has it increased by lung capacity. I recently lost 23 pounds and I feel better. I have cut down the use of my rescue inhaler dramatically. I use to use it daily now I use it once a week or so.I always thought it made no difference, but I guess if you'r overweight like I am losing weight makes your diaphram go down so your lungs have more room to expand. it hasn't cured my problem but I breath much easier.I still get a lot of phlem exc, can't breath in humidity, but generally breath better.So far no trips to the er(cross my fingers)
