Given roll, not as lethargic (8)
I believe the answer is:
listless
'lethargic' is the definition.
(similar in meaning)
'given roll not' is the wordplay.
'given' is a charade indicator (letters next to each other).
'roll' becomes 'list' (list can mean to lean or roll).
'not' becomes 'less' (I've seen this in other clues).
'list'+'less' is 'LISTLESS'.
'as' is the link.
(Other definitions for listless that I've seen before include "Lacking energy or interest" , "Short of energy (and ill-equipped for shopping?)" , "Lacking zest or vivacity" , "Lacking energy or vitality" , "Without energy or vitality" .)
