Some people experience memory lapses when intoxicated.
Alcoholic memory lapses, or alcoholic palimpsests, are fragments of more or less erased memories or total loss of memory about everything that happened during the period of intoxication.
This is a symptom characteristic of the second stage of alcohol dependence.

Memory problems occur because the brain is damaged to such an extent that mental processes are disrupted. In addition to amnesia, there are, for example, aggression, rigidity.

Alcoholic oblivion indicates that the pathology is becoming organic.
In severe forms of addiction, degenerative changes are irreversible. But most often, problems related to memory can be eliminated, however, only if the patient maintains long-term sobriety, ideally throughout life. In this case, the organic pathology of the brain will be leveled, and not only memory and performance will improve, but also the quality of life of a person.
Hmm. Not an expert, but actually the first episodes of amnesia after drinking alcohol are already such… advanced stage. I would, jokingly enough, ask myself if this is definitely not already alcoholism. That is, a symptom that is already characteristic of the disease; although you never know how you react individually (- if you ask yourself).
In fact, alcohol affects each person differently. Let's say I'm starting to get sleepy, and some of my friends are getting ready for adventures. Moreover, the amount of alcohol consumed deepens these states. Well, if you look at these things from a scientific point of view, then you need to first understand why intoxication occurs. Very roughly, we can say that the liver is very actively fighting alcohol, and trying to process it, for this it secretes certain enzymes, but due to these processes and changes in the composition of the blood, blood cells lose the protective fat layer, and begin to stick together, which leads to blockage of small capillaries. It is mistakenly believed that only the brain and liver suffer from alcohol, this is not true, since all internal organs are affected. Due to the blockage of capillaries, in particular the brain, brain cells begin oxygen starvation, after which neurons begin to die, that is, what we used to call intoxication is nothing more than a special case of oxygen starvation of the brain. Along with neural connections, we also lose our rational thinking. And here, as it seems to me, the most primitive instincts come into play, the level of their expression depends on the person's temperament, that is, all drunken antics are built on this. And trying to remember what happened yesterday with a hangover in the morning suggests that neural connections in the brain region responsible for memory take a bigger hit at the stage of incipient intoxication than others.
Well, first of all, it should be noted that the alcohol molecule, although not a mediator, nevertheless affects the neurotransmitter systems of the brain and, depending on the dose consumed, affects the dopamine- (activation) or gaba-(inhibition) systems. If you take a large dose (from half a bottle or more, depending on the constitutional and enzymatic characteristics of the body), all the mediator systems begin to suffer and a certain “malfunction” occurs in the work of nerve cells. This, in turn, affects the process of perception of information in general and the transition of this information from short-term memory to long-term memory, which, in my opinion, is the main reason that sometimes, after large doses of alcohol, we do not remember anything.
