I've read some of the other questions on this site about how to write a drunk person (this link, this link, and this link) but what I'm not clear on is writing a drunk person's train of logic and how they justify their choices.
In my story, I have a scene where a character gets really drunk and then makes a choice that they would never make sober and that no one regardless of opinion would consider logical. I'm writing in first person and have never been drunk myself. The choice in the story is one where the character is given the option to either accept or decline an offer and they have time to think about it, so I need to have a quite long and wild string of thoughts leading to their choice. How do I show this character's illogical justification for their action?
To be clear, the links that I've looked at have shown writing from the drunk person's POV (I think I'll be good on that) but I don't know how exactly to write the train of logic. Should I make their thoughts fast? Slow? How do I connect the logic leaps? How far should the logic leaps even be? When faced with a difficult choice, would a drunken person panic/be violent irrationally or would they be stupidly happy?
