Levofloxacin
"I was sick for several weeks. I assumed it was sinusitis again.  I became more tired and feeling progressively worse. We had our annual physicals scheduled which was fortunate. I had pneumonia. I was given 7 days/750 Levaquan. The drug is very effective in clearing the infection. The easiest way to avoid sleepliness or disrupted sleep is to take in A.M. Given the efficacy of the drug, and the ability to minimize any annoying side effects, it is a good choice. While side effects are troublesome for some the results of untreated pneumonia can be far worse."
