One patient screaming for a hypodermic injection to relieve her pain was given an injection of sterilized water and the pain vanished. Another just could not sleep without her bromide. The nurse fixed up a powder of sugar, salt and flour; the patient took the powder and went to sleep. That was mind control and mental longing satisfied. Another patient had to take something to stop her pains; she got capsules of magnesia. The capsule satisfied her longing, established her faith and gave her relief; the relief was through her mind and not through the capsule. [Sidenote: Changing Thought Direction.] I have seen several weary, despondent patients fretting and wearing themselves out over their so-called weakness and run-down condition. I have placed copies of "Pep" in their hands and watched courage, faith, cheer and serenity come to them. It diverted their minds from self-thought and self-accusation to faith-thought, confidence and courage. You can think of only one thing at a time, and "Pep" or any other book that can change the thought habit from fear to faith, from worry to peace, is doing a service. I've been in shadowland in the hospital to see for myself the actual help that mental control will bring to sufferers, and the evidence is far above my powers to describe. I've seen the patient's eyes brighten up when the cheery surgeon came with hope, smiles and confidence on his face. I've seen the drooping of spirits when well-meaning but poor-expressing friends came into the patient's room and condoned and sorrowed with him. Verily, "as a man thinketh in his heart, so is he." Verily, good cheer and good thought are good medicines. And to these truths all good doctors say "Amen!" 15. [Sidenote: The Pill Fiend.] How often we see the pill fiend. In his vest pocket he has a small apothecary shop--a collection of round paste-board boxes and little bottles. Every little while he dopes himself. If his stomach is on a strike, he pops in a pill. If his head aches, he takes a tablet. If he sneezes, he takes a cold-cure pill. When anyone around speaks of a pain or ache, he hands the person a pill. The pill eater is a hypochondriac, and very likely his doctor knows it. His salvation is that the doctor probably gives him harmless stuff in pill form. The patient doesn't know this, and it's like a rabbit's foot or a piece of pork rubbed on a wart--it satisfies the mind and nature makes the cure. Often, however, the pills are not innocent; the pill fiend buys the tablets and pills direct from the druggist. The headache tablet is most likely one of the coal tar drugs like acetanilid, and that is positively harmful when taken too often. There are times to take pills--in cases of emergency, when you can shock nature with a poison and bring a wholesome reaction. These times are rare, and the doctor should be the sole judge as to when such treatment is necessary.
