bronchitis
"My bronchitis was so severe that the only way I would be able to board my flight to South America in 3 days was with the z-pack.  I took 2 pills right at the doctor's office and headed back to the office. I was in complete disbelief when within 3 hours of taking the first 2 pills my overall condition had improved tremendously.  I am glad that I didn't experience any adverse symptoms while on it, but I know of some people that unfortunately are not able to take this medication."
