If you can’t imagine starting your morning without a triple espresso shot or at least a hot cup of Joe (see our blogger’s logo), you’re not alone. Eight in 10 adults claim to be consumers. But a new study suggests that coffee doesn’t really give us caffeine fiends the jolt we think it does – it just returns us to a normal state of alertness after a night of withdrawal. So why do some people become drawn to caffeine in the first place, and others never touch the stuff? “One can speculate, people who may be suffering some symptoms of depression may be more attracted to caffeine because of its mild stimulant,” Dr. Petros Levounis, director of the Addiction Institute of New York, told NPR.
