Therapeutically it can hardly secure an effect which cannot better be secured through the real sleeplike hypnotism. Under certain conditions, chemical substances may well prepare for the hypnotic treatment, for instance bromides or alcohol. Others rely on the suggestive effect of flavored water. But all that is unwise. The confidence of the patient is the best preparation for the securing of the helpful degree of hypnotism. Of course only a small part of the therapeutic usefulness is secured during the hypnotic state itself. A pain may be removed, sleep be secured, an idea be inhibited, a movement be reenforced in cases where non-hypnotic suggestions would have found insurmountable obstacles. During the hypnosis we may also open the storehouse of memory and bring to light the ideas which disturbed the equilibrium of the suffering mind. Further in those most complex hysteric cases of dissociated personality, new memory connections may be formed during the hypnosis by which a synthesis of the double or triple personalities into the old one may be secured. Yet the general effect which the physician has to hope for from hypnotic treatment is the post-hypnotic one. Not what happens during the hypnosis but what the suggestion will produce after hypnosis is essential to him. The fixed idea is to disappear forever, the paralyzed limb is under control, the desire for morphine and cocaine is gone for all future time, the perverse longing is annihilated, the old energy is to remain again for all time. It is the post-hypnotic after-effectiveness which gives to the hypnoid and to the hypnotic states their importance for the treatment of the most exasperating symptoms. To be sure, the treatment often must be a prolonged one. A man who for years has used thirty grains of morphine a day cannot be rid of the desire after two or three hypnotic sittings. In such a case the treatment may cover three or four months, if it is to be of lasting value and without any damage during the treatment.
