After a drink, most people become more sociable, less stressed, and happier, and will probably reach for another drink before too long. For all this to occur, the alcohol in the drink has to do a multitude of things. When you sip that tasty gin and tonic , the ethanol goes to your stomach and small intestine, where it is rapidly absorbed into your bloodstream. Some of the ethanol gets broken down in the liver to give you energy about 7 kcal per gram , and some of it gets to the brain.
Once in the brain, it starts interfering with various kinds of neurotransmitters—the messenger molecules that tell different parts of the brain to start or stop various activities. Alcohol blocks the effects of glutamate and enhances the effects of GABA, so the overall result is that alcohol acts as a depressant, making you more sociable and relaxed.
Because of its sedative effects, alcohol makes falling asleep easier. However, it reduces the quality of sleep , because it decreases the amounts of two of the three phases of sleep—the slow-wave and rapid-eye-movement REM phases. REM sleep is also to critical to memory formation, and it is one reason why drinking too much is associated with blackouts.
Drinking can also numb pain—not just emotional distress, but actual physical pain. This it achieves by dampening down the pain signals that sensory neurons send to the brain. It also stimulates the production of dopamine, the chemical associated with many pleasurable activities such as sex, good food, and playing video games.
Dopamine is a key part of the reward-motivation system in the brain.
