Ha, if true that would confirm Balzac's claim: > Coffee is a great power in my life; I have observed its effects on an epic scale. Coffee roasts your insides. Many people claim coffee inspires them, but, as everybody knows, coffee only makes boring people even more boring. From "The Pleasures and Pains of Coffee, 1830, http://blissbat.net/balzac.html
This part resonated with me:
> When you have reached the point of consuming this kind of coffee, then become exhausted and decide that you really must have more, even though you make it of the finest ingredients and take it perfectly fresh, you will fall into horrible sweats, suffer feebleness of the nerves, and undergo episodes of severe drowsiness.
I definitely get extremely drowsy any time after 5 pm when I have gotten into the habit of drinking plenty of coffee per day
