caffeine becoming my main source of energy

Insane how i consume way too much caffeine for a person my size. In one day, for today for example i had a starbies coffee, a black coffee and an energy drink. Guess what i'm still tired, functioning but tired. I feel like its never ending especially at the age where my son is at rn i'm constantly doing something even when he's sleeping i have to rub his back. He no longer wants to stay in his crib. I depend on all that caffeine bc of of my little one. Even so i enjoy every bit of it <3
