Different people can handle different amounts of caffeine. It depends on how much you weigh, and how used to it you are.

Now that Pumpkin Spice Lattes are back, some of us might be drinking way more than we usually do. So here are some signs you're getting more caffeine than your body can handle:

  1. You get the shakes. It's because your central nervous system can't handle the amount of caffeine you've had. You just have to wait for your body to metabolize it.
  2. You're way too hyped. Too much caffeine can also cause panic attacks, anxiety, insomnia, heart palpitations, and even explosive anger.
  3. You have to pee a lot. Obviously it has to do with all the water in coffee. But it's also because caffeine is a diuretic. Too much caffeine can even make you dehydrated, so being thirsty all the time is another sign you've had too much.
  4. You feel confused or disoriented. A little caffeine can help you concentrate, but too much can have the opposite effect. You end up feeling confused and ramble a lot.
  5. You crash really hard at the end of the day. When you're tired, your brain produces a compound called adenosine. Caffeine prevents it from doing its thing, but you keep producing it. When the caffeine finally wears off, you get a rush of it all at once that makes you feel exhausted.
