Though there may be no specific for insomnia in the drug store, the complaint can often be relieved when the cause is wholly physical by striking at its root. If the general practitioner fails to relieve disturbances of the digestion, the stomach specialist should be consulted. One of my patients, who had for two years suffered both from insomnia and other troubles which had exhausted the ingenuity and the resources of the local doctors he consulted, began to improve as soon as a stomach specialist of national repute to whom I sent him discovered by chemical analysis of the contents of his stomach an incredibly excessive acidity, for which the proper prescription and diet were at once suggested.9

In cases where insomnia is evidently due to some physical ailment which cannot be at once located, a visit to the oculist, the dentist, and even the throat and nose specialist should as a matter of course be paid even if the patient has no conscious need of them. In at least two instances which have come under my observation, the insomnia disappeared after proper treatment of the eyes and teeth and throat, though two general practitioners had suspected nothing wrong in one case with the eyes, and in the other a visit to the throat specialist was never once suggested by the doctor who sent the case to me for the Emmanuel treatment.
