Most of us use coffee, tea, and energy drinks on such a regular basis there’s a good bet we take them for granted. But did you know that it’s possible to have a caffeine overdose? Most people don’t even realize it until it’s too late, but it far more common than you think. Somewhere between the second and third cup of Starbucks during the day, we’re willing to bet some of you might be feeling twitchy, thirsty, or even dizzy and anxious.
It may sound ridiculous, but caffeine is an addictive drug that can lead to some serious health issues. It can adversely affect brain chemistry… and that’s something you really don’t want to screw with. In the worst cases, it can even kill you. Don’t believe us? Check the list below and find out the dangers posed by caffeine.
You Can Suffer Permanent Nerve Damage
It’s been reported in the book Advanced Nutrition and Human Metabolism that caffeine negatively impacts the effects of adenosine in the brain. That, in turn, leads to increased blood flow to your brain. In small doses, this increased blood flow makes you feel awake and alert, but too much can cause headaches, dizziness, seizures, or loss of motor coordination. Too much caffeine can also lead to vitamin B-6 and B-12 deficiencies, resulting in permanent nerve damage.

If you have too much caffeine in your system, your body will start to react as if it has been poisoned. And, as with many poisoning episodes, it will do everything it can to expel the toxins from your body. That means vomiting… and a lot of it.
You Can Become Really Paranoid
Caffeine effects dopamine transmission, and too much dopamine will lead your brain into some really dark places. If you drink too much coffee, chances are that you will start to feel paranoid. So if you start believing all the crazy conspiracy theories out there, chances are it’s time to cut back.
You Can Get Dangerously Dehydrated
Coffee is a diuretic, which means the more you drink, the more you’ll be using the bathroom. While to some this may seem like a mere inconvenience, it can lead to some really big problems. Losing that much water that fast is can be very bad for you - not to mention the fact that getting up in the middle of the night to urinate can negatively affect your sleep.
In addition, caffeine can cause you to lose essential nutrients quicker than you can replace them.
