It may surprise you that the most commonly used drug in the world is caffeine. Caffeine can be a great pick me up that helps get you through the day. Plus, quitting caffeine can cause annoying side effects like headaches and nausea. However, while it may seem harmless enough; there are studies that suggest negative effects of excessive caffeine use. Before you make a decision to give up or cut back on caffeine, be sure you have all the information.

Having been a college student, I know the negative effects of too much caffeine. While caffeine may help you get a jump start during the day or stay up all night studying, too much can make you nervous and shaky. It can also cause your heart to race and even affect your breathing. If you find yourself a bit jittery or shaky, caffeine may be the culprit. Plus, caffeine can make you feel more stressed during the day, even if you haven't had too much.

Your afternoon caffeine boost may be to blame for your insomnia. A lot of people think caffeine won't keep you up if you don't drink it before bedtime, but the stimulating effects of caffeine can last up to 6 hours. If you cut back your afternoon caffeine consumption, you may find yourself more rested in the morning.

Along with the side effects of caffeine; studies have suggested that there are more serious consequences from excessive use. Its stimulant properties can have negative effects on the heart including high blood pressure. Its diuretic effects may cause calcium loss, leading to osteoporosis. In addition, it's been suggested that caffeine can raise cholesterol, cause stomach irritation, and may even be linked to certain cancers. While most of this research is inconclusive and linked to high consumptions of caffeine, it's something to think about.

Caffeine has not only been linked to low birth weight, and miscarriages; some also suspect that it could prevent conception. If you're pregnant or trying to conceive, you should seriously consider giving up caffeine.

While research suggests that caffeine may be bad for you, quitting is ultimately a personal choice. If you feel you just can't get through the day without your coffee, try drink less throughout the day. You may feel withdrawal symptoms to begin with, but you'll be much better off in the long run.
