How Can Severe Cough At Night Be Treated?

I feel fine, or I think I do, and ALL I do is COUGH......COUGH......COUGH!! Mostly at night when I go to bed and !I am eating. However, I go out to the living room and sit in a recliner to sleep and still wake up about 3 or 4 times a night coughing. When I do cough, it comes out really deep and loud, I can t BREATHE!! Most of the time I go in the bathroom and throw up. It leaves me weak. I m sorry, I just ran across this website, I don t have the money to pay for your answer. Thank you!
