I use a Cefaly, I got it for migraines. I use it almost daily I love it!!! I did not get the USA version it only has 1 setting and it hurts. I got one from amazon.ca.com Canada. It has 3 settings, it helps with anxiety, depression, sleep. It costed about $350.00 best investment I've made.

I think it is similar in theory and proposed results-but not sure if mechanism is the same. There are a couple of other brands out there, too.

I've never heard of the Fisher Wallace Stimulator. Is it like TMS - transcranial magnetic stimulation or ECT? I'll have to look up this treatment.
