Sleep after sex, getting up before end of day in confused state (5)
I believe the answer is:
tizzy
'confused state' is the definition.
(I've seen this before)
'sleep after sex getting up before end of day' is the wordplay.
'sleep' becomes 'zz'.
'after sex' becomes 'it' (a common euphemism. I am not sure about the 'after' bit.).
'getting up' shows that the letters should be reversed in order.
'before' says to put letters next to each other.
'end of' suggests the final letters.
The last letter of 'day' is 'y'.
'it' in reverse letter order is 'ti'.
'zz' put after 'ti' is 'tizz'.
'tizz'+'y'='TIZZY'
'in' is the link.
Can you help me to learn more?
(Other definitions for tizzy that I've seen before include "State of emotional excitement" , "Confused state" , "State of agitation" .)
