Dr. Pai has spent almost forty years researching sleeping and non-sleeping patterns (the more indoor illumination, the less sleep necessary). He contraindicates sharply the 3 million pills swallowed nightly in England and Wales, 15 million in the U.S. as harmful, addictive and potentially fatal. (For those walking in the shadow of the valley of the dolls, however, Anthony West in his current articles The Drugged Society has evidence that for the 3000 deaths from barbiturates, twenty million people ""used them without ill effect."") For chronic insomnia, chiefly an anxiety state, Pai has three programs which have proved valuable, the Tenlax method (muscle relaxing), Pranayama (deep breathing) and Nidra (a little of each). They have worked at his Sleep Center. He writes briefly about associated factors but the value of his short and stringet ""discourse"" is his recommendation to take a deep breath instead of a pill and his claim that it will work as well and serve you better.
