I have found out by using this device for a very short period of time that in some ways it does help. By this I mean that I still get a feeling of anxiety sometimes but not a much as I was having before I started using the S/C system. I have kind of given up on the ust of the S/C system during the night but using it more in the early morning and afternoon. I do get the windowing effect that the literature talks about but its the sound cure noise seems to disappear not the T's. I have also notice one thing also when I have the device on after a few minutes I cannot hear the noise that the S/C is putting out but as soon as I remove the ear buds and replug them into my ears the noise is back. Why I do not know? Anyway like they ust to say in the old days! Just keep on trucking!
