I have been using the FWS for about ten months. I have mood disorder, anxiety/insomnia. It has helped my mood disorder/ anxiety considerably. I have been able to lower my medication more than half. I struggle a lot with insomnia, however have not used stimulator as directed. I will try to use the stimulator 20min twice a day to see if I can make some progress. I would definitely recommend the FWS to those who want to lessen using medications.
