apple as substitute for coffee?

Tweet

Ive stumbled upon article claiming that eating an apple or drinking its juice is better than having a cup of coffee , when u feel like sleeping but u need to be up ,like when youre at work . I think i would go for the apple aside from it's a fruit it doesn't have caffeine , wherein u get perk but by the time you wish to sleep u won'tbe able to cause of the caffeine effect.
