I have suffered from clinical depression for most of my adult life. I have been in therapy for more than fifteen years, and I have tried most of the SSRI Anti-Depressant medications on the market, during that time, with marginally positive results; which is to say, that the meds plus therapy seemed to help prevent me from sinking into the depths of the depressive stupors that I had gotten used to. But still there was rarely any sense of real mood elevation. About a year ago I invested in the FW Stimulator and shortly after I began using it I noticed that I was experiencing with much more frequency a muted kind of elation. It wasn’t dramatic, but it was noticeable. I’ve not used the Stimulator the suggested two times a day, but I am impressed that the change which has taken place has continued. My only complaint has to do with replacing the wire leads that run between the sponges and the unit. Mine had gotten caught on the corner of an end table and separated. The FW is a good unit.
