Nice! That's the thing, right? That's the key I don't think people understand.

My normal energy level, once I've woken up for a few minutes, is how I used to feel when caffeinated, after having been on the stuff for awhile.

The low energy they feel, is literally the caffeine addiction talking. Your body gets so used to it, you're not feeling the buzz you felt when you first tried it, you're just maintaining a normal human level of energy, but it feels like a buzz because without it your brain is so addicted that it's suffering for it.

Crazy.

Now I still have a little caffeine for a really bad headache I can't shake. But it only takes a few sips of coffee or pop, and I'm good. It's not enough to make me feel wired, but I still might struggle to fall asleep that night, when normally I don't struggle at all.

Caffeine IS powerful, people just get used to it, but their body is still affected every day.
