Sinusitis
"I have taken Avelox on several occasions for sinusitis and bronchitis and within two doses, I always feel 10 times better! I am aware that dizziness and nausea can be side effects, but since I have taken it before bed, this has never been an issue.  I am surprised at the number of people who try to take it during the day - take it at night and you will tolerate it just fine"
