My Lady Nicotine (A Study In Smoke)

"I was a mere bachelor, drifting toward what I now see to be a tragic middle age. I had become so accustomed to smoke issuing from my mouth that I felt incomplete without it; indeed, the time came when I could refrain from smoking if doing nothing else, but hardly during the hours of toil. To lay aside my pipe was to find myself soon afterward wandering restlessly round my table. No blind beggar was ever more abjectly led by his dog, or more loath to cut the string."
