I can share the experience of a 40 year old man who has suffered from anxiety all his life. His doctor put him on two pharmaceuticals (sorry, don't know which... the most common, probably), but he didn't like the side effects, nor were they very effective. Then he did online searching, and ended up buying a Cranial Electro Stimulator (Fisher Wallace in his case), which had a night-and-day effect. He is so glad he found this. I'm sure other manufacturers might work as well. Also, I think tDCS (transcranial direct current stimulation) might be even more effective, but cannot be purchased directly.
