The effect of opium, the reader must bear in mind, always lasts twenty-four hours; but its higher, more refined and stimulating influence exists but a few hours, when it sinks into the soporific effect, which extends over the remainder of the time. In the advanced stages of the opium habit, the stimulating influence, if there be any at all, lasts but a few minutes. I mean, that is, the pleasurable sensation and revival of the spirits; there may be at times or always an almost imperceptible stimulation which obtains a short time after taking a dose of opium, but this is an effect entirely different from the pleasurable sensation, though it may exist with or follow it for a short time. This I may term stimulation without sensation. A person's body may be so deadened by opium that it can no longer produce sensation, but may produce slight stimulation for a short time. One may become conscious of this by an increase of power in the faculties of the brain, and in the temporary removal of the obstructions that weigh upon the brain, and which the poor opium eater so often suffers from. "Suffers from?" Days upon days my head has felt as though it were encircled by an iron helmet, which was gradually becoming more and more contracted, until it would literally crush my skull. Add to this the distress so often experienced in the region of the epigastrium (pit of the stomach), which, perhaps, more at one time than another, but which does always, impair the working of the brain for the time being, and often cuts off almost totally the use of the mind, and what is left of a man mentally is very little indeed. Yet all these miseries he must endure, and more; but of these in the proper place, for we must now return to the subject properly in hand,--the first stages of opium eating,--from which I beg the reader's pardon for having digressed too far.
