While experimenting with nunca in negative sentences for a while, my instinct kept telling me to include the definite article in one particular construction, where it would not be required in any of the others.
ie. Never eat sweets before dinner (imperative)
= No comas nunca LOS dulces antes de la cena
Could you clarify for me 1) if the article is actually required here at all, or 2) if it could be used correctly as an option.
