Hangxiety

Anxiety is one of the myriad of causes that the consumption of alcohol produces and the reason why most people resort to drinking in the first place. It’s like a chicken and egg situation. Maybe we have a little bit of (or a great deal of) anxiety as a result of traumas that have happened in the past leaving us feeling unworthy, undeserving and not accepted, or because we were shy and reserved; maybe we had not or were not given the opportunity as children to develop enough confidence that would have allowed us to feel like we could “survive” in a room with people we didn’t know. There are as many reasons as people on the planet. As most of us know, what alcohol does is give us an instant chemically induced feeling of relaxation, but if we keep on drinking, a burst of anxiety will ensue hours later. How does that happen, I hear you say? In straightforward terms, this is how.

Alcohol and Neurotransmitters

There are many neurotransmitters in our brain. Neurotransmitters are chemicals that transmit messages between our neurons and our brain cells. I always picture them like tiny Pac-mans with tiny back-packs with stuff in it. The two core neurotransmitters that are like the on-off switches of the brain are GABA (gamma-aminobutyric acid) and glutamate. GABA turns the brain off (sleepy) whilst glutamate switches it on (wakey). They are like two best friends who compensate each other. We need both of them to have a balanced system so that when one is released, the other is too.

Relaxation

The feeling of relaxation is caused by alcohol releasing more GABA, which has a calming effect. Valium does the same. This is why our exhibitions are lowered, why we feel we can be more friendly and even fearless. But if you drink too much, the amount of GABA released turns off your pre-frontal cortex, which is the executive centre of your brain that allows you to make sensible decisions. This is also why, after a couple of drinks, it is very likely to keep on drinking because that rational part of the brain goes offline. The more you drink, the more GABA is released, and the more your brain becomes incapacitated to work correctly, affecting the part connected to language and motor problems (i.e. slurring, falling off). If you drink heavily, your brain might turn off entirely, and that’s when you can stop breathing (alcohol poisoning). At the same time, the alcohol starts to block the glutamate receptors, which keeps you awake and alert because the brain always seeks to restore balance. This process is called homeostasis.

Hangxiety

The anxiety caused by alcohol is so established that it has gained its unique nickname over the years. It is by far the most common mental health issue associated with drinking. So, what brings that up? As I mentioned before, when you start to drink, your brain releases more GABA (the sleepy neurotransmitter) and decreases glutamate activity (wakey, wakey).

Also, the more ingrained your habit becomes, the more your brain will slowly stop producing GABA – even when you are not drinking – because it knows that the alcohol supplies it. As the brain always seeks to achieve homeostasis, it will increase glutamate because it does all it can to keep you alive.

When you wake up in the morning after a heavy night, while the alcohol is wearing off and slowly leaving your system, you are left with that massive amount of glutamate, which it had previously activated, and that’s what creates your anxiety. It’s like a seesaw with an elephant on one side and a squirrel on the other. This causes stress on its own, and, of course, it piles up on the anxiety that you already have. You were drinking to cope with anxiety, and on top of it, as a cherry on the cake, you experience the added the stress because of something embarrassing you might have said or done or something you don’t remember – a phenomenon called black-out.

I have found that knowing how alcohol works makes a huge difference in the process of contemplating consuming alcohol, moderating or stopping altogether. Personally, the reason I like a scientific explanation is because it’s objective. It’s a chemical reaction which happens in our brain, and it happens to everybody.

For me, it’s like the difference between knowing someone as an acquaintance vs living with them and discovering their true colours.
