But first, it may help to understand the science behind that throbbing, queasy, mouth-full-of-cotton malaise. According to Dr. Christine Lay, a neurologist at The Headache Institute at St. Luke's-Roosevelt Hospital Center in New York City and co-author of an upcoming article on hangovers in the journal Headache, the culprits are:

• Dilation of blood vessels. This may contribute to the throbbing headache.
• Low blood sugar. Alcohol can interfere with the liver's ability to produce glucose, which leaves you feeling weak and tired, clouds your thinking and makes you moody.
• Poor sleep. While alcohol is sedating and promotes sleep initially, the sleep is often of poor quality with frequent awakenings due to factors such as decreased rapid eye movement (REM) sleep.
• The accumulation of toxins. The main byproduct of metabolized alcohol, acetaldehyde, is a toxin that can make your heart race and lead to headache, sweatiness, flushed skin, nausea and vomiting.
• Dehydration and electrolyte imbalance. Alcohol promotes urination by inhibiting the release of the brain hormone that normally protects against dehydration. When dehydration is accompanied by sweating, vomiting or diarrhea, there is additional fluid and mineral loss leading to electrolyte imbalances The result? Excessive thirst, lethargy, dizziness and light-headedness.

So, if you do consume too much alcohol, drinking plenty of water is essential because dehydration is perhaps the most common cause of hangover symptoms.
