Caffeine Addiction Can Be Serious

Oleksii Afanasiev/Thinkstock(NEW YORK) -- Like just about anything else, it’s possible to get hooked on caffeine to the point where trying to kick the habit can produce some very unpleasant withdrawal symptoms.

Professors from American University, Johns Hopkins University School of Medicine and the University of Vermont got together to learn more about problematic use of caffeine, which most can consume without it ruining their lives.

However, some people aren’t so lucky, according to the researchers, since the stimulant may cause “physical dependence, interferes with daily functioning, and can be difficult to give up.”

And here’s the kicker: the researchers admit that scientists still know so little about caffeine dependency that they’re not exactly sure how to help people break their addiction.

What they have learned is that physical and psychological symptoms do exist and some people can’t give it up even if they have a heart condition or bleeding disorder.

To play it safe, the researchers say people should limit coffee to two-to-three cups a day or the equivalent of 400 milligrams of caffeine.  Those with physical problems or mental issues such as anxiety or insomnia should try to consume even less caffeine.
