Consume Product

It's basically common sense that something that makes you feel so good and gives so much energy is at the expense of of something else. It's engineering trade off.

Besides what the other people wrote, there is a reason why coffee is always given for free everywhere (office jobs, hospital, car dealership). Coffee makes you okay with bullshit. It makes you feel productive, useful and creative even when not. Read caffeine blues, look at mri study about caffeine cutting blood flow to brain. See how spider webs look when on caffeine vs. other drugs.

After quitting caffeine, I see the manic personalities of other caffeine drinkers around me. They don't shut the fuck up, they constantly interrupt and have the 40 cocks in college crazy eyes. I have more vivid dreams and no hangovers (stomach digestive and blood flow problems).
