pneumonia
"Initially self-diagnosed myself (I like to avoid doctors as much as possible) and determined that I had bronchitis.  Started taking Mucinex twice a day and Tylenol every four hours for three days.  When cough didn't improve dragged myself to the doctor and was diagnosed with pneumonia.  Prescribed 250 mg Levofloxacin;  by Day Two I was able to start breathing again without it being laborious to do so.  Now on Day Five and feeling MUCH better.  Only warning:  eat BEFORE you take this medication  (unless you're looking to lose weight) and drink a lot of water!"
