caffeine crash
Post-coffee energy collapse
A caffeine crash is the wave of fatigue and sluggishness that follows the stimulating effects of caffeine wearing off.
As caffeine blocks adenosine receptors, adenosine builds up; when the caffeine clears, the accumulated adenosine hits all at once: I had three espressos this morning and now I'm in a full caffeine crash.
The crash often leaves people more tired than before they had coffee.
