Out of bed, drunk and tense (7)
I believe the answer is:
uptight
'tense' is the definition.
('uptight' can be similar in meaning to 'tense')
'out of bed drunk' is the wordplay.
'out of bed' becomes 'up' ('up' can be a synonym of 'out of bed').
'drunk' becomes 'tight' (I've seen this in other clues).
'up'+'tight'='UPTIGHT'
'and' is the link.
(Other definitions for uptight that I've seen before include "Highly-strung" , "Informally, nervously tense and anxious" , "Unable to express one's feelings" , "nervy state" , "On edge" .)
