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. "
The only ones that bother me are the ones used repeatedly in the same series. I finished a trilogy earlier this year(I forget the name) but every fight scene I’m it a parent dies, all the younger generation have plot armor but all the old people die. It got very predictable, and happened at least 10 times.
