I have lived with severe, resistant anxiety and depression secondary to PTSD for 20 years. I’ve used this device for CES almost every day for the past two months—per my device, a total of 93 hours—and it has made a MASSIVE difference in my quality of life. It took several weeks to notice the full benefit for the depression, but the effect on anxiety was immediate and dramatic, to the point that I can use the device to abort panic attacks within minutes. My mood is MUCH better, any dips are much shallower and briefer, and the worst side effect is a little dizziness during a session if I need to walk around. I’m not thrilled with the price of the consumables but given the dramatic difference and near total lack of adverse effects, I can live with it.
