People who drink, say everyday, without being alcoholic (and I mean this objectively) are able to recognize the stage at which they are during drinking. They understand and keep in mind the downside, the headache and dehydration etc. In other words the brain although enjoying the moment is aware of the situation.
The alcoholic will ignore the downside. They take every drink of vodka (usually) as if it is the first. The first drink that gives them that rush of pleasure. They seek that. They want to recreate that. The pleasure is "getting out" for a while.
They seek that rush. That opt-out from life. They think that it happens every time you drink for the first time. It does not. Beyond a certain amount of alcohol or point in time the downside outstrips the upside. The alcoholics don't recognize this which inevitably leads to a long binge in the case of Jane with disastrous consequences for health, finances and relationships.
