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. "
I don’t like the character born good trope, which usually comes with battling someone I could have been trope. The reason this doesn’t work most of the time is because the “good guy” is usually just too dense to figure things out, alongside having a lot of convenient things happen in there life that takes away there ability to choose in the first place.
