energy crash
Post-sugar fatigue
An energy crash is a sudden drop in alertness and physical vitality, typically following a period of heightened activity or stimulation.
It often occurs when caffeine, sugar, or adrenaline wears off: I had a massive energy crash after my coffee wore off.
The term implies an abrupt collapse rather than gradual fatigue—you don't slowly tire, you hit a wall.
