Mislay zesty items sent over and fret overnight? (4,5)

'fret overnight?' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'mislay zesty items sent over' is the wordplay.
'mislay' becomes 'lose' (synonyms).
'zesty items' becomes 'peels' (I can't justify this - if you can you should give a lot more credence to this answer).
'sent over' shows that the letters should be reversed in order.
'peels' back-to-front is 'sleep'.
'lose'+'sleep'='LOSE SLEEP'

'and' is the link.

Can you help me to learn more?
