I've become very intrested in Binaural Beats lately, and I would like to find out about all of your experences with them. Please take part in the poll, and discuss your experences with them.

EDIT: I made a mistake with my poll, the "If you answered "Yes, it certainly worked" to the previous question," shouldn't be there. Regardless of how it worked, answer the question as "Where did you get it?". Thanks...
