People who drink coffee daily their brain chemistry changes.

The brain cell is now attempting to maintain the equilibrium so; it is now producing more adenosine on daily basis.

More adenosine will result in tolerance of caffeine, now the amount of caffeine a person is drinking have no effect on brain. therefore, a person need to intake more caffeine to block the adenosine.

 There the caffeine doze increases.
