Alcohol I consumed at food counter in a frenzy (8)
I believe the answer is:
delirium
'frenzy' is the definition.
(I know that frenzy can be written as delirium)
'alcohol i consumed at food counter' is the wordplay.
'alcohol' becomes 'rum' (alcoholic spirit).
'consumed' is an insertion indicator.
'at' means one lot of letters go next to another (I've seen this in other clues).
'food counter' becomes 'deli' (I can't explain this - if you can you should give a lot more credence to this answer).
'rum' placed around 'i' is 'rium'.
'rium' after 'deli' is 'DELIRIUM'.
'in a' is the link.
Can you help me to learn more?
(Other definitions for delirium that I've seen before include "An acutely disturbed state of mind" , "state of ecstasy" , "Feverish state" , "Wild enthusiasm" , "Disordered state of mind due to fever" .)
