Your mom says not to drink soda at night because the caffeine will keep you awake. And she says she "needs her caffeine" in the morning when she's reaching for her cup of coffee. So what is caffeine, anyway?
Caffeine (say: KA-feen) is a natural chemical found in tea leaves, coffee beans, cacao (the stuff used to make chocolate), and kola nuts (the plant that gives cola soda its flavor).

Today, caffeine is found in many common foods and drinks, such as coffee, tea, energy drinks, hot cocoa, soda, chocolate, and some medicines.
Caffeine is a stimulant (say: STIM-yuh-lunt). Stimulants make us feel more awake and alert. Many people have drinks with caffeine because they think it helps them to wake up and feel sharper.

If you'd like to cut down on caffeine, talk with your parents. They can help you understand how much you're getting and help you cut down.
Check the ingredient list on the label and choose caffeine-free or decaf drinks. If you don't, you might find yourself tossing and turning instead of snoozing and snoring!
