“Fanciful ideas rampant”

In 1911, the Coca-Cola Company tested the effects of caffeine on sixteen users and non-users. The test-subjects kept notes:

On Feb. 22, a regular user was caffeine-free: “Felt like a ‘bone head’ all day. My head was dull more than usual.” On Feb. 25, an abstainer was dosed with four grains of caffeine (260 milligrams, the approximate equivalent of a 12-ounce cup of Starbucks coffee): “Gradual rise of spirits till 4:00. Then a period of exuberance, of good feeling. Fanciful ideas rampant.”
They’re rampant here too, though I’ve been nearly caffeine-free for nearly a year — nothing more than a very occasional cup of caf tea and a very, very occasional cup of caf coffee (helpful before watching films with subtitles).
