Dark liquors (whiskey, red wine) have more congeners, which worsen hangovers.

FAQs About Hangover Duration
Can a hangover last more than a day?
Yes. Especially after heavy drinking, poor sleep, or dehydration, symptoms can linger 48–72 hours.
Why do hangovers get worse with age?
The liver slows down with age, and sleep quality often decreases—making recovery longer.
What if my hangover is still going after 48 hours?
You're likely dealing with residual fatigue or dehydration. If symptoms are severe, consult a healthcare professional.
