I've known people with disabling headaches until they hit 200mg+ of caffeine in the AM. They are caffeine addicts.

>you wanna do it every day, even if you get cranky when someone (sometimes you) ruin this ceremony for you

This is addicted behavior; the bar is far lower than most people use the word for.

The term addiction is commonly used to describe something else though.

Addiction for the most part is life shattering and not about 'having headache for a few days when not drinking coffee'.

Sure, withdrawal effects are a criteria for substance use disorder and I guess you could construct a mild disorder by finding some other criteria.

But nobody becomes homeless because of coffee consumption, nobody loses they job or friends because of it, nobody smokes or injects caffeine to have a greater effect.

You can call people drinking coffee addicted, but that only works for the effect because addiction is a terrible disorder, not because coffee consumption is that terrible.

Btw: I consume products that contain caffeine very rarely (1 per month maybe).

My father's one of those people who get a headache unless they get their morning cup of tea. That is what deters me from caffeine.
