Yes, when the two parts of the brain are fighting, the lower brain sub-conscious desire for alcohol (via its links to the higher brain i.e. AV) and the higher brain's conscious wish not to consume - if that struggle culminates in the decision to take a drink, as alcohol affects the brain - a sway seems to occur which alters the balance of power. Until the sway is complete and the balance of power is completely shifted to the lower brain and the person acts out as the lower brain does with its ugly, often regretful behaviour, eventually blackout occurs and the person is functioning, without retaining memories, until they pass out into unconsciousness and the sway is complete. Eventually, that became my experience, every time I drank.
