I'm about to blow
In my experience a good coughing fit has to end with a final, loud and phlegmy cough.
When I need to cough, I pretty much always need to cough three times. I think I was in my twenties when I learned this is not the case for everyone, and some people just cough once and are done. Once!!!!
