anxiety
"I have been taking 1600 mg for 35 years. It is the only medicine that my doctor tried that really worked to relieve my panic disorder. However, it is only currently being produced by one drug company, and they are really expensive. It is considered an "old fashioned" medicine. Right now my insurance is covering it with a $50 copay. I don't know of any other medicine that is similar, so I guess I'm stuck for now."
