How Can Bronchitis And Chronic Cough Be Treated?

I have had bronchitis but am about over that. I still cough phlegm up occasionally because it s loose. However, I am prone to have an out of control coughing attack when something like a crumb hits a certain place in my throat. It s scary to say the least because I have no control, can t talk, and can hardly breathe. It s very embarrassing because it s so intense. Sometimes if I feel a tickle there, I can grab some water and ward it off, but it difficult to get it in time. Is this normal? It has happened about several times this year.
