This question is regarding a dialogue of Hermia in Scene 1 of Act 1 of 'The Midsummer Night's Dream' by William Shakespeare where she mentions, "From lovers' food till morrow deep midnight." Please explain what the playwright refers to by "lovers' food."

I'd guess that this refers to some sort of poison that lovers choose to have when they are forced to break their relation or to some meal that lovers have with a great night ahead of them. I wish to have a confirmation on this.
