Please go off out for the night (6)

I believe the answer is:

asleep

'out for the night' is the definition.
(I've seen this in another clue)

'please go off' is the wordplay.
'go off' indicates an anagram.
'please' is an anagram of 'ASLEEP'.

(Other definitions for asleep that I've seen before include "Slumbering" , "Snoozing" , "this fast?" , "Resting unconscious" , "Like kippers" .)

I've seen this clue in The Irish Times.
