finished

'being exhausted' is the definition.
(I've seen this before)

'fished out a bit of wine' is the wordplay.
'out' indicates putting letters inside.
'a bit of wine' becomes 'ni' (I am not sure about this - if you are sure you should believe this answer much more).
'fished' enclosing 'ni' is 'FINISHED'.

Can you help me to learn more?

(Other definitions for finished that I've seen before include "Complete" , "exhausted" , "Brought to an end" , "Done, over, ended" , "wrapped up" .)
