I have a problem that affects me often: When I fill my lungs to capacity, I often have to cough. Sometimes I can hold it back and the sensation goes away, but often it doesn't and I have to cough, thereby expelling all my air. I suppose it's part of my general lung anatomy. I've had a problem all my life with upper respiratory infections, both viral and bacterial, and I almost never get a cold without it moving to my lungs, so something's going on there. Does anyone else have this problem? Has anyone else had this problem and found a way to overcome it?
