According to research conducted by Johns Hopkins University in Baltimore, Maryland, of the millions of North Americans who enjoy that daily caffeine fix, “about half…will experience headaches and other symptoms from caffeine withdrawal syndrome,” the article states.
The article quotes one regular American, Susan Todd, 59, of Michigan, who observed that “I can drink four or five cups, easily, comfortably.” If Todd misses a dose, however, it does not go unnoticed. "I feel lousy all over. It's not that anything hurts," she explained. "I just feel sluggish, and a cup of caffeine will cure that."
But why would caffeine trigger such a strong response in people? Michael Kuhar, chief of the division of neuroscience at the Yerkes National Primate Research Center at Emory University in Atlanta, Georgia, refers to caffeine as a “mild stimulant” and believes that people can become dependent.
"If you take a cup of caffeine you're likely to feel good and energized," Kuhar told CNN. But be warned. "Withdrawal symptoms can start from 12 to 20 hours after your last cup of coffee and peak about two days later and can last about as long as a week.”
For those concerned about the withdrawals, Kuhar recommends eliminating caffeine gradually, reducing consumption by a half to a whole cup per day.
