And I could not even go into an unlighted room after nightfall without the most terrifying feelings of abject fear. There was not a night came during a certain period without bringing with it the most harrowing and dreadful forebodings of death before morning. I must in justice state that I was using some quinine at this time to break up a fever that was continually attacking me, and that I was then again using morphia by means of the hypodermic syringe (having been induced to adopt that mode by another person who was using it in the same way,--which I found to be much more injurious than taking it per mouth); nevertheless, it was still the opium habit, and it was that which induced the fever, and made necessary the quinine. No tongue or pen will ever describe--mine shrinks from the attempt, and the imagination of another, without suffering it all, could scarcely conceive it possible--the depth of horror in which my life was plunged at this time; the days of humiliation and anguish, nights of terror and agony, through which I dragged my wretched being. But I am anticipating other and future parts of this narration. It is my intention to disclose, as I proceed, the effects of opium from the first dose, and commencement of the habit, till it reaches its ultimate and final effects, and to describe an attempt to renounce its use at the latter stage. Still, I have thought it proper, even at this juncture, to give the reader to understand that the opium habit, from first to last, produces nothing but misery,--and that of a kind entirely without hope in this world. This I expect to prove in detail as I proceed. CHAPTER VIII.
