However, you might want to arm yourself with this latest science about alcohol consumption:
Smoking and drinking makes your hangover worse, experts say:
Damaris J. Rohsenow of the Center for Alcohol and Addiction Studies at Brown University conducted the research with his team.
They surveyed 113 college students every day for eight weeks. According to a summary:
Overall, when students drank heavily -- the equivalent of five or six cans of beer in about an hour -- those who'd smoked more on that same day had higher odds of suffering a hangover the next morning and suffered more when they did.
The study is scheduled to be published next month in the Journal of Studies on Alcohol and Drugs.
At the same number of drinks, people who smoke more that day are more likely to have a hangover and have more intense hangovers.
Why? It's not clear. Researchers think "nicotine receptors in the brain are involved in our subjective response to drinking," according to the summary.
So, as you prepare for you holidays, remember that if you light up and drink, you'll suffer for it.
