Crisis On Holiday Sparked Recovery
- On a family vacation in Florida, Charles hit a crisis point after heavy drinking and contemplated suicide.
- That moment, plus AA and therapy, prompted him to stop drinking and begin recovery.
Why Hangovers Can Feel Like Withdrawal

- Individual differences in neuroplasticity likely explain why some people experience these withdrawal hangovers and others do not.
