What Would We Do Without Researchers?

Caffeine withdrawal is real.

[Insert Elaine Beniss-like "Get....OUT!"]

[A]nalysis shows as little as one cup of coffee can cause an addiction, and withdrawal from caffeine produces any of five clusters of symptoms in some people:

- Headache, the most common symptom, which affects at least of 50 percent of people in caffeine withdrawal

- Fatigue or drowsiness

- "Unhappy" mood, depression, or irritability

- Difficulty concentrating

- Flu-like symptoms such as nausea, vomiting, muscle pain, and stiffness.

"Onset of these symptoms typically occurs within 12 to 24 hours of stopping caffeine and peaks one to two days after stopping," Griffiths tells WebMD. "The duration is between two and nine days."

12 to 24 hours, my fanny. I wake up with all of them every day! It's only after I get my cup o' joe that they go away.

Coffee-crazed Yips! to Jen(nifer).
