Hello-
I just wanted to add a quick note that I was prescribed Levaquin several years ago to treat bronchitis and it gave me horrible insomnia. I would be looking at the clock at 2 am and wondering why I didn't feel tired at all. I had to be switched to a different antibiotic and then I was fine. At the time, my doctor thought it was "odd" that I experienced that side effect, but since then I've heard that the same symptom has been experienced by many, many people.
