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 MC having so many injuries but just pushing through the pain. Or never sleeping but pushing through it. Bodies just stop at a certain point. You can’t push through a broken ankle, at least not for long. And people need sleep, otherwise microsleeps and then hallucinations happen. But nope, the mc just keeps pushing through all of the injuries as they build up, For days or weeks.
