Use the noun treacle to describe a book or a song that is so sweet and sappy that it makes you feel a little sick.

Treacle is literally a type of thick, sticky syrup — that might help you remember its primary, figurative meaning as non-food that’s syrupy and sentimental. When someone lays on the flattery, that's treacle, as are overly sentimental music and calling your girlfriend "schmoopy-poo." Interestingly, the word treacle was originally used to mean "poison antidote," from the Greek root word thēriakē, "antidote for venom."
