Why Do I Get Hangxiety After Drinking?
Alcohol calms your brain while you drink, and when it wears off your brain rebounds the other way - that rebound is what feels like anxiety.
The simple answer
While you drink, alcohol turns up a calming chemical and turns down an alerting one. When the alcohol leaves, your brain tries to rebalance, and the calm can flip into feeling wired and worried. Broken sleep, lost fluids and replaying the night can pile on. Drinking more to calm it back down usually makes the rebound worse.
Myth vs Fact
A morning-after drink is the fastest way to settle your nerves.
More alcohol can stretch the anxiety out over days instead of letting it pass.
