Caffeine tolerance

Factual Questions
1

I read that it takes about two weeks of drinking coffee every morning to start developing a dependency/tolerance. If you only drink coffee five days out of seven, does that break or delay the cycle? What about four days out of seven? Three? What if you have your coffee every other day?

It depends on why you’re using caffeine.
