Bloated? Stop drinking dodgy lager! (8)
I believe the answer is:
enlarged
'bloated?' is the definition.
(thesaurus)
'stop drinking dodgy lager' is the wordplay.
'stop' becomes 'end' ('end' can be a synonym of 'stop'**).
'drinking' means one lot of letters goes inside another.
'dodgy' is an anagram indicator.
'lager' with letters rearranged gives 'large'.
'end' placed around 'large' is 'ENLARGED'.
(Other definitions for enlarged that I've seen before include "puffed out?" , "Increased, augmented" , "Expanded, amplified" , "Magnified" , "Made greater" .)
