Fisher Wallace creates a stimulator that is available for individuals to use in their home and clinical studies indicate is helpful in treating depression, anxiety, and insomnia. It also is also in the treatment of pain. I have one of these and have used it extensively when suffering through a major depressive episode. The cost is a few hundred bucks. I’ve never been able to conclusively determine whether it makes a significant difference for me, my depression has been too deep when I’ve used it, but the clinical studies are more convincing to me than many other available treatments and the cost is a few hundred dollars (not inexpensive by any means, but doable for those who are really struggling). I’d suggest it for those who are finding themselves unable to find healing or even comfort through other more traditional means (counseling, medications). If you happen to use it please let me know how you think it helped (or didn’t) in your situation!
