has anyone tried this? like a pre-recorded hypnosis for SA, self esteem, etc? i've been looking into it, there's a bunch of things like this out there on amazon & itunes..but i'm just not sure about it. & i dont really feel like wasting my money on something that is just a ploy to get money out of people that are suffering. i've also heard about this thing they're doing now with sounds..it's like listening to beats, frequencies, sometimes birds, waves, stuff like that. & apparently all this is put together for certain ailments, SA, weight loss, depression. anyone tried it/heard of it? did it work for you?
