This effort should be made with the advice and under the eye of an intelligent physician. So far as I have had opportunity to know, the profession generally is not well informed on the subject. In my own case I certainly found no one who seemed familiar with the phenomena pertaining to the relinquishment of opium, or whose suggestions indicated even in cases where the physician has had no experience whatever in this class of disorders, he can, if a well-educated man, bring his medical knowledge and medical reasoning to bear upon the various states, both of body and mind, which the varying sufferings of the patient may make known to him. Were there, indeed, no professional helps to be secured by such consultation, it is still of infinite service to the patient to know some one to whom he can frequently impart the history of his struggle and the progress he is making. Such confidence may do much to encourage the patient, and no one is so proper a person in whom to repose this confidence as an intelligent physician. The amount of time which should be devoted to the experiment must depend very greatly upon these considerations--the constitution of the patient, the length of time which has elapsed since the habit was formed, and the quantity habitually taken. When the habit is of recent date, and the daily dose has not been large--say not more than ten or twelve grains--if the patient has average health, his emancipation from the evil may be attained in a comparatively short period, though not without many sharp pangs and many wakeful nights which will call for the exercise of all his resolution.
