When one waits until some difficulty has passed, we say "wait something out". Is there a word/expression in English for sleeping until your hunger, pain, or negative emotions subside?
Sleep it off
to stop the bad effects of having too much of something by sleeping for as long as it takes to end those effects
For hunger specifically there’s a very modern phrase I’ve heard
Having sleep for dinner
But it’s so new that I can’t really find many references for it other than Urban Dictionary and Reddit/Twitter usage.
