The Lord of the Rings: The Return of the King is based loosely on the third book of The Lord of the Rings trilogy, written by the English academic and author J.R.R. Tolkien [1892-1973].
Red onion and garlic both stay on your breath for a long time, reducing the smell of alcohol. 1  You can order bar foods that contain onion or garlic. 2  Add red onions to a sandwich, burger, or salad after drinking. 3  Some people, if they're looking for a fast cure, simply eat onion or garlic raw.
In my experience, it depends a lot on what you are drinking. Wine and beer have a lot of sediment and live things in them and you can smell either one on someone's breath instantly. Red wine stains your teeth too, so that is another way to indicate that you have been drinking. Spirits are a little different.
