This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Maybe if you're already taking it regularly this is true, but we know that it blocks some adenosine receptors, preventing the buildup of adenosine, which is one component in making us feel sleepy.
Yes it makes you feel less sleepy/tired but it doesn’t ’give you energy’ - just tricks the body into thinking it’s less tired than it actually is
This feels like grammar nitpicking.
If someone is feeling sleepy/tired which interferes with them doing whatever, and something got rid of that sleepy/tired feeling, most people would say that thing gave them more energy.
That's not true. It sounds like you're confusing nicotine with caffeine. Nicotine is often credited with "taking the edge off" when in reality, that "edge" is a result of nicotine withdrawal.
Caffeine blocks the receptors that react to a chemical the body releases when it's tired. You're right that it doesn't give you more energy, but it does stop you from feeling by tired.
Out of all the common legal drugs (nicotine, alcohol, THC) caffeine actually provides some of the best benefits with least intrusive drawbacks.
Making you not sleep isn't really the same as giving you energy, and since most people take it in the morning anyway it doesn't really matter
I know you said "gives you energy" originally, but is that how most people think of coffee? I tend to think of it as "When I drink this I'll be less tired."
