Doxycycline
"Fought off a sinus infection that went into my chest and turned into bronchitis. I absolutely hate taking antibiotics, but after a couple months with a bad cough, which was actually starting to go away, I developed pleurisy. I had decided I would have to go see the Doc. He prescribed me this and an anti-inflammatory. It started working on the second day and by day seven it was gone. I did not have any side effects. I had never taken this before, so might be why it worked so fast because I thought the pain was going to kill me."
