sinusitis
"My doctor always prescribes Levaquin for bad sinus infections and congestion because of my many drug allergies.  I LOVE Levaquin.  Within hours of the first dose all of the mucus in my head and/or chest starts to make a mass exodus.  At times, the volume and swiftness that it drains can choke you -- but this medicine works and it works FAST.  It's made me cough so hard I gag, but all of my coughs are super productive, if not overly so.  I recommend this to anyone wanting to get better and back in the saddle at warp speed."
