Discharged for nothing more than a drunken doze (5)
I believe the answer is:
oozed
'discharged for nothing' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'more than a drunken doze' is the wordplay.
I cannot quite see how this works, but
an anagram of 'doze' is 'ozed' which is located in the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oozed that I've seen before include "Leaked out slowly" , "Seeped" , "Exuded" .)
