Caffeine Addiction UI300 K Farwell, PhD, RN, CARN-AP
Caffeine Addict Speaks Out "I was a coffee junkie," Hoff wrote. "I'd drink a cup in the morning just to get out of the house, and then another cup on the drive to work. But I wasn't done when I got to my desk job at the law firm–not by a country mile." In her frank, seven-page article, Hoff confessed that she, like an alarming number of professional women in the U.S., got on "the coffee train" to help meet the demands of a hectic lifestyle. "I was making three or four, sometimes five trips back to that [office] coffee maker," she wrote. "It's free, it's fresh, and it keeps you chug-chug-chugging along through your busy day. Sooner or later, though, that kind of habit will catch up to you." Recovering caffeine addict Joanna Hoff, who shares her difficult tale in the April Woman's Day.

Caffeine Withdrawal Headache Caffeine is very similar in structure to another chemical in our body called adenosine. One of adenosine's jobs is to dilate blood vessels in the head. Caffeine blocks this dilation. Your body then has to become more sensitive to adenosine to compensate. The only problem being that when caffeine is withdrawn, your body is overly sensitive to adenosine and blood vessels will dilate, creating a pounding headache.
