LOL! the first day i got a headache too! i just thought and laughed a lot from my friends that i didn't focus to the sound by any bit, and after a few attempts my head started hurting

Maybe it can't take away the effect of the alcohol, but it can clear your mind out, and return in to a normal state, but the alcohol is still there, so I think it might take off the dizzyness, but all the other effects stay, well thats how I think

Well if your so skeptic, and strong minded on that, then you might not get the effect, its as good as you believe in it too, at least for me, but try your friends, don't tell them whats there, just tell them to concentrate on the sound, you should get a good laugh at it and you'll see that it works ...
