Duloxetine
"To the gentleman whose doctor switched him from Klonopin to Cymbalta:  The reason you are suffering from severe anxiety is that you were taken off a Benzodiazepine too quickly instead of having been TAPERED off the drug.  Cymbalta is no substitute for Klonopin. Your doctor needs to go back to med school!  I've been taking 60 mg of Cymbalta since 2009, after my husband committed suicide. It has helped me a lot with depression and anxiety, but I'm finding that my anxiety has recently increased because my new husband has lung cancer. I was put on 90 mg of Cymbalta recently, and I'm hoping that the higher dose will decrease, and not increase, my anxiety levels."
