I just started taking Levaquin for throat pain and problems that my doctor is not sure what they are. Since taking, I am shaky and full of panic, crying almost non-stop for no reasons at all, my heart races, stops, races. I am having trouble getting to sleep and when I do wake up with horrible nightmares. It won't go away. Should I call my doctor? Stop taking? I am at a complete loss. My doctor was an idiot...
