Like, honestly, this is a pretty universal advice:
You may love coffee, but if you *need* a coffee, what you're needing isn't the caffeine boost, it's the thing that's making you need a caffeine boost.
If you can nap, that means you have the time, the ability, and the opportunity to take the nap. That happens far less than your opportunity to get or make a coffee, which takes less time.
Ergo, just take that fucking nap.
And if you still feel like shit after, THEN you can take that coffee.
@tariqk yummmmmm, chocolate.
