Nope, coffee won't give you extra energy. It'll just borrow a bit that you'll pay for later

But there is a catch. While it feels energising, this little caffeine intervention is more a loan of the awake feeling, rather than a creation of any new energy.

This is because the caffeine won’t bind forever, and the adenosine that it blocks doesn’t go away. So eventually the caffeine breaks down, lets go of the receptors and all that adenosine that has been waiting and building up latches on and the drowsy feeling comes back – sometimes all at once.

So, the debt you owe the caffeine always eventually needs to be repaid, and the only real way to repay it is to sleep.

I have long suspected this and now I know it's Scientific Truth.

I always have a cup of black coffee before I go to sleep. Sleep great every night!
