Query: Relief is here!

Perhaps you suffer from insomnia, and this book came up in a random search for books on the topic. If you are truly seeking help with your sleep disorder, do not, I repeat, DO NOT overlook this book merely because it is a work of fiction, and will offer very little in the way of scientific illumination of your problem. Make no mistake about it, if you are an insomniac, this is one book you absolutely MUST have. With few exceptions, the mere act of READING this book offers a more expedient cure than a thousand prescriptions of your pharmacist's most powerful sleeping aid.
