bacterial infection
"Levaquin knocked my bacterial or sinus infection out in 20 days.  I was having headaches every morning for months and not sleeping well.  This really stopped my infection.  I could tell that the infection was busting up because my headaches stopped and my sleep improved significantly.  The headaches were like something squeezing on my brain that would not allow me to think well most of the day.  I was not sleeping well at night and tired most of the day.  This made all the difference and has put me back to normal.  There is a tremendous difference in my daily work, alert, awake, and sleeping performance after the treatment cleared up my infection.  "
