Dr. Marc Galanter , a professor of psychiatry at New York University School of Medicine in New York City, agrees that drinking too much period is the root cause of a hangover, regardless of the alcoholic weapon of choice.
"What's clearly emerged is that it's the alcohol content that is the most salient factor in terms of damage and long-term damage and addiction," he said. "It's the actual amount of alcohol that counts. Nonetheless, we see emerging some interesting issues in terms of which congeners go along with which alcohol. For example, in terms of what produces more hangover."
"So research like this points to the fact that there are other peripheral issues which have some import and are worth exploring," he acknowledged.
To avoid a hangover, the National Institutes of Health (NIH) suggests drinking slowly, on a full stomach, with water and in moderation. For women, the National Institute on Alcohol Abuse and Alcoholism recommends no more than one 12-ounce drink per day. For men, no more than two drinks per day.
For those who are already saddled with a morning-after head-pounding, the NIH recommends plenty of rest -- noting that hangovers usually dissipate within 24 hours-- while consuming food and liquids containing salt, potassium, and fructose, which is found in fruit juice and honey.
