Alcohol switches off your decision-making center first.

The very front part of your brain, right behind your forehead, is called the prefrontal cortex. Think of it as the 'adult in the room.' It handles planning, self-control, and thinking about consequences. Alcohol targets this area first. When the 'adult' goes to sleep, your filter vanishes. You might say things you normally keep to yourself, buy things you cannot afford, or think dancing on a table is a fantastic idea. You feel brave, but really, you have just lost your warning system.
