Myself against myself? For the moment (8)
I believe the answer is:
meantime
'for the moment' is the definition.
(I've seen this before)
'myself against myself?' is the wordplay.
'myself' becomes 'me'.
'against' becomes 'anti' (I've seen this before).
'myself?' becomes 'me'.
'me'+'anti'+'me'='MEANTIME'
(Other definitions for meantime that I've seen before include "For the moment" , "interim?" , "interval" , "Intervening period" .)
