I was just wondering how many people on this site has Gerd or acid relux ... I never smoked except for forty years ago... Fourteen years ago I started with having problems with Acid reflux.. I have read that the gases go up then settle into your lungs. I have a cough all the time that started years back and lung infections all the time that caused they told me fibrosis none spending from all the lung infections I got... My feeling is I ended up with pr emphaysema from acid reflux... I went on a pill for acid refllux and I pill at night to thin emucus no coughing or phlegm in the morning . I havn't even had my blue puffer at all in ten days... Just wondering if any one come up with the same theory..
