Holosync Demo

Listened to the Holosync Demo this evening, and it left me feeling completely brain-dead. For those of you that don’t know, Holosync is a company which produces a neurotechnology that is supposed to induce meditative states. I’ve heard quite a few people have gotten tons of value out of this product (including some very close friends of mine), but all I’m left with is a terrible headache and a few fried neurons. I guess that could be good :\ ?
