As somebody who has had about 1 sip of coffee in their entire life, how significant is the effect? I currently don't understand when people say that they need a coffee to 'wake up'.
Does drinking the coffee actually make you feel more awake (as if you had more hours sleep), or does it just increase response times while you still feel tired?
