Caffeine withdrawal occurs when a person who consumes caffeine on a very regular basis suddenly stops altogether. However, some people who quit caffeine abruptly will find they can do so without any symptoms. If a person does develop caffeine withdrawal, symptoms usually begin 12 to 24 hours after the last dose of caffeine and last a couple of days. Withdrawal occurs because the body has become dependant on caffeine. People who consume two or more servings of caffeinated beverages are more likely to experience withdrawal than those who have just one small cup of coffee a day.
