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. "
Or when they do this and each chapter is a different POV, like A Game of Thrones series. So you might not be coming back to that character until the next book. Which may not have been printed yet. And may never…
I found myself skipping chapters to get back to the same characters again, otherwise I’d forget the cliffhanger.
