Myth No. 1: Caffeine is addictive

Facts: Well, this depends on what you consider "addictive." Caffeine is a stimulant to the central nervous system, and regular use of caffeine might cause mild physical dependence-but caffeine doesn't affect your life the way addictive drugs do, and thus most experts don't consider caffeine dependence an addiction, per se. When regular caffeine consumption is quickly halted, some of us experience symptoms that last from one to several days-this can be avoided if caffeine consumption is reduced slowly.

If you've tried to stop cold turkey, you have experienced one of these symptoms:

• headache
• fatigue
• anxiety
• irritability
• depressed mood
• difficulty concentrating
