He who makes up his mind to it can rest almost as well without sleep as with it, provided he keeps his mind calm and his body relaxed. "Decent hygienic conditions" demand not necessarily eight hours of sleep but eight hours of quiet rest in bed. Tossing about drives away sleep and uses up energy. I make it a rule that my patients shall not turn over more than four

times during the night. This is more important than that they should sleep. To be sure, I do not stay awake to enforce the rule, but most people catch the idea very quickly and before they know it they are sleeping.

How to Go to Sleep

Ceasing to Care. The best way to learn to sleep is not to care whether you do or not. Nothing could be better than DuBois's advice: "Don't look for sleep; it flies away like a pigeon when one pursues it." [58] Attention to anything keeps the mind awake, and most of all, attention to sleep. More than one person has waked up to see whether or not he was going to sleep.

All I did was to explain to her that her body had been getting all the sleep it needed, and that neither body nor mind was in the least run down after twenty years of sleeplessness. "When you cease being interested in your insomnia, it will go away, although from a health standpoint it matters very little whether it does or not." We had two conversations on the subject, and a week later she came back to tell me that she was sleeping eight hours a night.

One woman had had insomnia for thirty years. After I had explained to her that her body had adjusted itself to this way of living and that she need not try to get more sleep, she snored so loud all night and every night that the rest of the family began to complain!

A certain banker proved very quick at catching the idea. He had been so troubled with insomnia and intense weakness that his doctors prescribed a six-months voyage in Southern waters. Knowing that my prescriptions involved a change in point of view rather than in scene, he came to me. Although he had been getting only about half an hour's sleep a night, he went
