Ironically, I get bronchitis pretty much every year, too. Mine triggered my "excercise induced asthma" into regular ol' daily asthma. So, when I start wheezing, if a shot or two from the inhaler (and a boost in vit C) doesn't do the trick in a few days, it's time to go fill the zithromax pack script I keep in reserve. Thankfully that does the trick, although I definitely move slow until it kicks in. As for pneumonia, I now get the pneumonia vaccine every 3-5 years, which so far means the bronchitis hasn't turned into that, at least *knock on wood*. If you haven't had that yet, get it. I don't bother with a flue shot, but I keep that pneumonia vaccine up to date.
