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 to sleep in his chair the first evening, and then went upstairs and slept all night. He resumed his duties at the bank, walking a mile and a half the first day and three miles the second. During the months following, he reported, "No more insomnia." =Keeping Account.= A bright young college graduate came to me for a number of ailments, chief among them being sleeplessness. She was also overcome by fatigue, having spent four months in bed. A four-mile walk in the cañon and a few other such outings soon dispelled the fatigue, but the insomnia proved more obstinate. After she had been with me for a week or two, I took her aside one day for a little talk. "Well?" I said as we sat down. Then she began: "Sunday night I was awake from half-past one to four, Monday from twelve to one, Tuesday from one to three, Wednesday from two to four, Thursday--" By this time she became aware of the quizzical expression on my face and began to be embarrassed. Then she stopped and laughed. "Well," she said, "I did not know that I was paying so much attention to my sleep." She was bright enough to see the point at once, gave up her preoccupation in the all-absorbing topic and promptly forgot to have any trouble with so natural a function as sleep.
