Other coffee drinkers include Voltaire of whom Tesla said:

"Thereafter I devoted myself chiefly to physics, mechanics and mathematical studies, spending the hours of leisure in the libraries. I had a veritable mania for finishing whatever I began, which often got me into difficulties. On one occasion I started to read the works of Voltaire, when I learned, to my dismay that there were close to one hundred large volumes in small print which that monster had written while drinking seventy-two cups of black coffee per diem. It had to be done, but when I laid aside that last book I was very glad, and said, "Never more!"

Tesla himself, in his autobiography, said of coffee:

"Long ago I suffered from heart trouble until I discovered that it was due to the innocent cup of coffee I consumed every morning. I discontinued at once, though I confess it was not an easy task. In this way I checked and bridled other habits and passions, and have not only preserved my life but derived an immense amount of satisfaction from what most men would consider privation and sacrifice After finishing the studies at the Polytechnic Institute and University, I had a complete nervous breakdown and while the malady lasted I observed many phenomena, strange and unbelievable..."

Which he went on to discuss...

Myself, I wrote three quarters of a novel in one week under the influence of the two liters of coffee I would consume during the morning. Energising it is; yet recalling the pitiful results of caffeine on arachnids and that so many verbs related to story-telling are shared by them (spinning a tale, weaving a story, following a narrative thread) perhaps we do better to avoid it?
