I didnt cough at all when i was a kid ( except for the usual colds i got). I think i started coughing in my late teens early 20's, i truely dont remember because i didnt cough a lot at all. I started having a more common cough as i got older. When i got cepacia at 31-32 years old thats when the daily cough started. How much i cough depends on how well i am doing. Most times if i am sitting here watching tv , or if i am driving my car, i dont cough often at all. When i am active is when i cough most. Walking up a flight of stairs i breath heavily and cough sometimes once i am at the top. Walking on the treadmill i cough a bit, sometimes more than others (and sometimes not at all). Like i said, it all depends on how well i am doing. When i am well i cough probably every hour or so , maybe even every half hour ( i never took notice) When i am not well i cough a whole lot.
