I am a horribly chronic insomniac... and these tapes put me to bed within 10 minutes. It's amazing. John Selby knows exactly what is wrong with the insomniac mind and releases the horrendous anger, anxiety, and stress so effectively it is almost as if you've taken a powerful sleeping pill... except it's better than that because you are in control of your mind...not a drug! I have a hard time sleeping with noise and this has helped me a lot. THANK YOU JOHN!!
