The final decision of the question, How long a time should be allowed for the final relinquishment of the drug? must, I imagine, be left to a wider experience than has yet been recorded. The general strength of the constitution, the force of the will, the degree of nervous sensibility, together with the external circumstances of one's life, have all much to do with its proper explication.
The general directions I should be disposed to suggest for the observance of the confirmed opium-eater would be something as follows:
1. To diminish the daily allowance as rapidly as possible to one-half. A fortnight's time should effect this without serious suffering, or any thing more than the slight irritation and some other inconveniences that will be found quite endurable to one who is in earnest in his purpose.
2. For the first week, if the previous habit has been to take the daily dose in a single portion, or even in two portions, morning and night, it will be found advisable to divide the diminished quantity into four parts. Thus, if eighty grains has been the customary quantity taken, four pills of fifteen grains each, taken at regular intervals, say one at eight and one at twelve o'clock in the morning, and one at four and one at eight in the evening, will be found nearly equal in their effect to the eighty grains taken at once in the morning. A further diminution of two grains a day, or of half a grain in each of these four daily portions, will within the week reduce the quantity taken to fifty grains, and this without much difficulty, and with positive gain in respect to elasticity of spirits, arising, in part, from the newly-awakened hope of ultimate success. A second week should suffice for a reduction to forty grains. It will probably be better to divide the slightly diminished daily allowance into five portions, to be taken at intervals of two hours from rising in the morning till the daily quantity is consumed. With such a graduated scale of descent, it will be found at the end of two weeks that one-half of the original quantity of opium has been abandoned, and that, with so little pain of body, and so much gain to the general health and spirits, that the completion of the task will seem to the patient ridiculously easy. He will soon learn, however, that he has not found out all the truth.
