sinusitis
"I have used Avelox twice before, and took it at night as my doctor said there might be dizziness or sleepiness.  Then I didn't need it for several years until this week.  On my third dose, my sinus infection already feels like it has gone, but I can't fall asleep and my thoughts are racing - I would say agitated.  I'm not sure if I can take this for seven more days.  "
