Three coworkers head to a bar after a long day. They decide to go shot-for-shot, all of the same poison, and it gets a bit out of hand. An hour later, one coworker is foaming at the mouth, looking to fight any mammal in sight; another is crying uncontrollably and stomping on their jacket; the third is delighted by the other two, giddily recording the whole thing. Uh… what’s going on here? Research on the effects of alcohol yields some clues: It may be possible to predict how people will behave when they’re drunk way before . Parrott, D.J., Zeichner, A.

Freedom of Slurred Speech — The Need-to-Know

Alcohol is a disinhibitor, meaning it in our brain, leaving us feeling more impulsive, less anxious, and (and sometimes broke).

Here are a few types that may sound familiar:

The Manhattan

Alcoholism, Clinical and Experimental Research. 2002 Sep;26(9):1350-8.. (Shocker, we know.) Researchers describe these folks as impulsive and short-sighted. And forget breathalyzers— a blood test might reveal who’s likely to pick a fight with the coat rack. There’s evidence that, in males and females, certain genes predict the ability to control anger, which affects sober and drunk behavior . Johansson, A., Santtila, P., Corander, J. et al.

Kamikaze

Tequila Sunset

The Drowsy Drunk. Take me drunk, I’m home. Unlike heavy drinkers, people who rarely have more than a sip of Chardonnay tend to feel sedate when they drink . King, A.C., de Wit, H., McNamara, P.J., et al. Department of Psychiatry and Behavioral Neurosicence , The University of Chicago, Chicago, Il, Archives of General Psychiatry 2011; 68(4): 389-99..

Experts' Take

We reached out to Glamourgirlz Experts Jason Edmonds and Jessica Magidson for their insights on the effects of alcohol.

Jason Edmonds: Alcohol tends to amplify certain personality traits-- such as aggression, amicability, etc-- but it won't typically create a 180 degree change. For example, a person who habitually becomes aggressive when intoxicated likely has tendencies toward aggression and frustration when sober as well. They might be able to better control these emotions when sober, but they're still present on some level.

Jessica Magidson: Although we'd like to think that there's a single explanation out there for what predicts if you are a "happy" or "sad" drunk before the night begins, that may not be the case. What often predicts how we'll act when drunk is a combination of numerous factors, many of which we probably don't have control over. The individual brings some things to the equation, some that can be seen as more stable (i.e., personality, genetic factors), and some situational (i.e., how much did you eat that day? how much sleep did you get?), but the reality is that this "mixes" with the environment one is drinking in, both in terms of who and what is around you and what you are drinking.
