The principal mode of action of caffeine is as an antagonist of adenosine receptors found in the brain. The reduction in adenosine activity results in increased activity of the neurotransmitter dopamine, largely accounting for the stimulatory effects of caffeine. Caffeine can also increase levels of epinephrine/adrenaline, possibly via a different mechanism. Acute usage of caffeine also increases levels of serotonin, causing positive changes in mood.

The precise amount of caffeine necessary to produce effects varies from person to person depending on body size and degree of tolerance to caffeine. It takes less than an hour for caffeine to begin affecting the body and a mild dose wears off in three to four hours. Consumption of caffeine does not eliminate the need for sleep: it only temporarily reduces the sensation of being tired.

With these effects, caffeine is an ergogenic: increasing the capacity for mental or physical labor (Hyperactivity)

Because caffeine is primarily an antagonist of the central nervous system's receptors for the neurotransmitter adenosine, the bodies of individuals who regularly consume caffeine adapt to the continual presence of the drug by substantially increasing the number of adenosine receptors in the central nervous system. This increase in the number of the adenosine receptors makes the body much more sensitive to adenosine, with two primary consequences : First, the stimulatory effects of caffeine are substantially reduced, a phenomenon known as a tolerance adaptation. Second, because these adaptive responses to caffeine make individuals much more sensitive to adenosine, a reduction in caffeine intake will effectively increase the normal physiological effects of adenosine, resulting in unwelcome withdrawal symptoms in tolerant users (agitation, anxiety, etc.)

In large amounts, and especially over extended periods of time, caffeine can lead to a condition known as caffeinism. Caffeinism usually combines caffeine dependency with a wide range of unpleasant physical and mental conditions including nervousness, irritability, anxiety, tremulousness, muscle twitching (hyperreflexia), insomnia, headaches, respiratory alkalosis and heart palpitations. Furthermore, because caffeine increases the production of stomach acid, high usage over time can lead to peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease.

i used to be addicted to coffee, i used to drink it every morning sometimes twice a day, and if i didnt drink it every morning i would feel drowsy the whole day. I thought i could never wake up if i didnt drink no coffee. Then my mom told me to stop it, and when i did, at first it was hard, but now i wake up every morning feeling hyper without it. I read somewhere that caffeine is addictive and u dont need to have it in order to feel hyper. It is all mental. So i dont drink coffee no more and i am absolutely fine.

I think Angelo's answer can make u hyper.

But calm down now. Breathe.... Good girl. Tell me who got u on ur nerves???

Caffeine can make u hyper if u take it in big quantities. Did u know that a cup of coffee is good for you? It actually makes u concentrate better. But it's effects aren't instantaneous. They can take up to four hours. that means that u can have a cup of coffee before going to bed with no problem.

Why do I drink it? I don't. I eat it. I love chocolate.
I have 2 coffees a week at most.

It doesn't make me hyper, but if I have too much, my heart starts racing...it's a scary feeling.
But I generally don't drink straight caffeine (is that even possible??:D)...just coffee, tea and sodas...because I like them.
