Run out of energy drinks - and energy! (6)
I believe the answer is:
elapse
'run out' is the definition.
(thesaurus)
'energy drinks and energy' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mc2).
'drinks' becomes 'laps' (lapping is a kind of drinking).
'and' is a charade indicator (letters next to each other).
'energy' becomes 'e' (physics symbol as in E=mc2).
'e'+'laps'+'e'='ELAPSE'
'of' acts as a link.
(Other definitions for elapse that I've seen before include "Go past" , "run by" , "Go by - pass away" , "(Of time) go by" , "Please (anag) -- pass away" .)
