“Woe to you, my princess, when I come. I will kiss you quite red and feed you till you are plump. And if you are forward you shall see who is the stronger, a gentle little girl who doesn’t eat enough or a big wild man who has cocaine in his body,” wrote Sigmund Freud to his future wife, Martha Bernays, on June 2, 1884. On February 2, 1886, toward the end of another letter to Bernays, Freud wrote, “Here I am, making silly confessions to you, my sweet darling, and really without any reason whatever unless it is the cocaine that makes me talk so much.” The two married later that year.

In An Inquiry into the Effects of Ardent Spirits upon the Human Body and Mind, published in 1785, physician and Founding Father Benjamin Rush wrote that drunkenness, an “odious disease (for by that name it should be called),” appeared with, among other symptoms, “unusual garrulity…unusual silence…a disposition to quarrel…uncommon good humor and an insipid simpering or laugh…disclosure of their own or other people’s secrets…a rude disposition to tell those persons in company whom they know, their faults…certain extravagant acts which indicate a temporary fit of madness.”
