Caffeine has a stimulating effect on the central nervous system, and consuming caffeinated beverages such as coffee, tea, soda or energy drinks will typically result in a feeling of increased energy, alertness and improved concentration. Caffeine is addictive, however, and if you develop a dependency and then reduce your caffeine intake, you are likely to experience symptoms of withdrawal such as sleeplessness, mood changes, and restlessness or jittery sensations.
Controlling Caffeine Intake
Limiting your coffee consumption to no more than 200 to 300 milligrams -- two to four 8-ounce cups of coffee or tea per day -- is typically an effective way to control your caffeine levels. Caffeine levels can vary depending on the serving size and brand of the coffee or tea, so check your beverage caffeine content.
Caffeine Addiction
According to the U.S. Food and Drug Administration, heavy daily caffeine consumption may result in addiction. You body will grow accustomed to the stimulating effects that caffeine has on your central nervous system, and you are likely to feel that you need coffee or another caffeinated beverage to wake up, stay focused or maintain energy levels throughout the day.
Caffeine Withdrawal
If you develop a dependency on caffeine and cut back on your intake, you are likely to experience associated side effects such as headaches, stomach discomfort, sleeplessness and jittery sensations. These symptoms may last for several days, depending on the level of your addiction and how quickly you cut back on your daily intake of caffeine. A small amount of caffeine can often help ease intense feelings of restlessness, muscle tremors or jittery feelings caused by caffeine withdrawal.
Expert Insight
If you're planning on quitting or cutting back on your caffeine habit, MayoClinic.com recommends you taper your use over a period of several weeks. Alternating caffeinated beverages with decaffeinated coffees, herbal teas or water can help you cut back in a more gradual manner, and you'll be less likely to experience intense withdrawal symptoms.
