Hey,
My sister and a couple of friends had it in the spring - yeah, the cough is NASTY and it just seems to hang on. My sister was hacking for at least two weeks or so, she felt a little run down (my friend was still out sailboarding through it!) both said they had some difficulty catching their breath if they pushed themselves too much.
One of my cousins, unfortunately, ended up in ICU with pericarditis and fluid in her lungs. She was there for about a week but was still hacking/coughing when they released her, so it seems the cough is the most distressing symptom.
Hope you start to feel better soon.
