I have a problem with severe dry cough attacks that seem to be triggered from sudden temperature changes and sometimes when eating. By temperature change I mean when I get in a cool vehicle when its hot outside is one example I have experienced. I have these attacks 3 or 4 times a day. There is white mucus that accompany these fits. The attacks last anywhere from 30 to 60 seconds. Sometimes longer. Breathing is difficult at time of attack.
