I was given Levaquin for a sinus infection. I just took one dose and was up, running at full speed for the next 30 hours. What a horrible experience. I had the sweats, my heart was racing, I could not sit or stand still. I had a major panic attack. Lost my appetite and had this bad taste in my mouth even when just drinking water. I tried everything to get this drug out of my system. I called my doctor and she told me that she was sure it wasn't the Levaquin, but if I wanted to I could stop taking it. You bet I will stop taking it and will never take it again!
