take leave of one's senses

Lose one's mind

To take leave of one's senses is to act irrationally or go temporarily crazy: Have you taken leave of your senses? You can't quit your job with no savings.

The phrase suggests a departure from reason, as if sanity were a place one has abandoned.

It often appears in exasperated questions directed at someone whose judgment seems catastrophically impaired.
