That jolt you feel from a morning "cup of Joe" may all just be in your head.

A new British study suggests that people who normally kick start their day with a strong cup of coffee, are no more alert than people who are not regular coffee drinkers.

Researchers at Bristol University found coffee addicts may only feel better, because they are counter-acting the effects of caffeine withdrawal.
