Try the story "Guts" if you're curious.
loving christ I can not even bring myself to read that again.
I'm not queasy or someone who vomits easily, it pretty much never happens unless I'm sick or something, but "Guts" was the most nauseating and disgusting thing I've ever read, what amplifies that story also is that it's not some spooky spookeronio hunting down the protagonist, it's something that is entirely real, has happened before, and is just so realistic and descriptive it's just. ehaugh god damn forget that stuff never reading it again.
