Caffeine linked to physical and emotional problems

by Otis Day

Caffeine dependence can be so strong, physically and emotionally, that it becomes a big problem.

Doctors have a term to describe it - caffeine use disorder - and researchers are developing addiction remedies.

There are reports that up to 90 percent of people in the U.S. regularly drink coffee and most don't see caffeine as a dangerous drug. It's safe in small doses and even in excessive amounts, but the worst are symptoms like headaches, anxiety and jittery hands.

Most people can cut back on caffeine without quitting, which isn’t like addictive drugs such as alcohol or heroin. Most people don't even know for sure how much caffeine they're drinking, because amounts can vary. A mug of coffee brewed at home may have 100 milligrams of caffeine, while a 16-ounce beverage at Starbucks can have more than 300 milligrams.
