Caffeine on net suppresses stress systems and improves many cellular level functions. Reams of epidemiological data strongly indicate the equivalent of four or five cups of coffee a day is good for you. If caffeine makes you jittery or causes other signs of increased adrenaline that means you are probably in poor health. Note that it's best to take it with food or a bit of sugar and taking it while hungry or low on glycogen can cause a bit of stress. Coffee is nothing but calming for me and I have zero withdrawal symptoms if I go a day or two without it.
