Revolting drunk may get one in a nervy state (7)
I believe the answer is:
uptight
'one in a nervy state' is the definition.
(uptight can mean nervous or tense)
'revolting drunk' is the wordplay.
'revolting' becomes 'up' (I've seen this in other clues).
'drunk' becomes 'tight' (I've seen this before).
'up'+'tight'='UPTIGHT'
'may get' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for uptight that I've seen before include "Tense or angry" , "Tensely repressed" , "Unable to express one's feelings" , "Tense, nervous, repressed" , "Repressed and disapproving" .)
