High doses of caffeine (750 to 1200 mg/day spread throughout the day) administered daily, have been shown to produce "complete" tolerance (i.e., caffeine effects are no longer different from baseline or placebo) to some, but not all of the effects of caffeine. However, lower or typical dietary doses of caffeine produce incomplete tolerance. For example, sleep may continue to be disrupted in regular caffeine users.
