Wow, so that sounds exactly like what I had about 2 years ago. I coughed and coughed for I don't even know how long. It was horrible, my back hurt so much during the coughing that I could barely stand while it was happening. I don't remember vomiting, but I do remember the initial sickness. I of course refused to see a doctor and it eventually went away.. but it was awful. ..then later that year I stepped on a nail and got and Kelsey forced me to go get a Tetanus shot. If only I had impaled my foot a few months earlier.

Anyway, I hope you get better. And I think I know just what will do it!
A really, really, reeaalllly long drive to Texas, arriving there Friday night just in time for my beach birthday bash! That will fix your right up. (Probably not.)
