Yesterday was Mardi Gras! If you have a headache, nausea, and an upset stomach, you’re not the only one. But which hangover cures can you trust?

The treatment: Hair of the dog that bit you

The verdict: Nothing doing. Hangovers are probably caused in part by dehydration. More alcohol will just dehydrate you further. Try a sports drink or coconut water to replace your missing electrolytes.

The treatment: Black coffee

The verdict: Mixed bag. Caffeine can help headaches – that’s why it’s in painkillers like Excedrin. On the other hand, coffee is a diuretic, and you’re already low on fluids. Some sources suggest trying a little bit of coffee and seeing how you feel.

The treatment: A cold shower

The verdict: Someone has a weird sense of humor. Cold showers are an excellent way to make a hungover person cold and wet. Aside from that, experts say a cold shower won’t help.

The treatment: Blowfish

The verdict: Ask your doctor. This new (and widely sold) tablet combines aspirin and caffeine – two time-tested remedies for hangovers. There are a lot of positive testimonials on their website, but you should always talk with a healthcare professional before taking a new supplement.

The treatment: Drinking responsibly

The verdict: Works like a charm. Doesn’t sound like fun? Neither does a hangover! Researchers consistently say that moderate drinking is the only surefire way to stave off the wrath of grapes.

On a serious note: If you’re concerned about your drinking, please talk to a doctor. We care about you, and we want you to take care of yourself.
