|7. The Habit: A Diet Coke Addiction|
If you can't get through the day without drinking Diet Coke, you may be hooked on caffeine. "There is about as much caffeine in one can of Diet Coke as there is in a shot of espresso," says Dr. Clayton. Having a few cans of Diet Coke a day could leave you feeling high, and then low when you come down from the caffeine buzz." Besides triggering major dips in energy, turning to Diet Coke as a pick-me-up makes it tougher to fall asleep in the normal 30-minute range come bedtime. Plus, the acidity in soda can damage tooth enamel if sipped daily.
Damage control: Limit your Diet Cokes to one per day, and don't drink any after 2 p.m. to keep the caffeine from interfering with your sleep patterns. Try rinsing your mouth with water after drinking soda to reduce the effects of its enamel-eroding acidity.
