The cardiologist gave them to me for pvcs. No way. I took them once and that was it. I'm surprised they are trying them for anxiety. Not sure what type you have but I have dealt with it most of my life. It's a long process, but for me drugs weren't an option. They make me more anxious! I meditate, but the biggest help for me was my bike and my dog. There are alot of things to go through, it doesn't happen overnight. But that's another story, PM me if you ever want to vent...
