I know this is probably a common topic. For me, I’m not sure if it’s a “trope” or just totally misinformed writing, but it’s how many authors approach alcoholism. Some examples are Girl on the Train and The House Across the Lake, among HUNDREDS. If anyone else here has struggled with alcoholism, you know it’s not just "i woke up after downing an entire bottle of whiskey but was able to shower, down a cup of coffee, and solve a murder. "
Similarly when a woman is drunk and the guy she is with DOESN’T make out with her/take advantage of her (the bare minimum) and he is seen as a hero. And then the woman thanks him for not taking advantage of her and she falls in love with him instantly.
