How caffeine affects people is highly individual.
That said, most people will respond to high caffeine consumption by developing sleep disorders -- insomnia of some kind.
Moreover, high caffeine consumption promotes anxiety. As we all know, worrying about something can keep you awake too, quite apart from whether your mind is just "racing".
Some people can drink a lot of caffeine and not be bothered, as long as the consumption is steady (about the same amount every day). Their bodies adapt to it. Not everyone is able to get used to caffeine, though, some people will always be very sensitive and really need to avoid the stuff to feel okay in themselves -- and get a decent night's sleep.
Children are more sensitive than adults, and young infants are the most sensitive of all. Breastfeeding mothers are sometimes advised to avoid caffeinated drink/food, because young babies get such a lengthy buzz out of mom's single cuppa. Then the baby gets extra ratty, because the poor thing is over-tired and unable to sleep, just because of the seemingly small dose of caffeine that came through in mother's milk.
