I believe the answer is:

egg-flips

I'm a little stuck... Click here to teach me more about this clue!

'drinks' is the definition.
(I've seen this before)

'goes berserk after say good strong' is the wordplay.
'goes berserk' becomes 'lips' (I can't justify this - if you can you should give a lot more credence to this answer).
'after' is a charade indicator (letters next to each other).
'say' becomes 'eg' (both can mean 'for example').
'good' becomes 'g' (abbreviation).
'strong' becomes 'f' (musical symbol for 'forte', 'strong' in Italian).
'eg'+'g'+'f'='eggf'
'lips' after 'eggf' is 'EGG-FLIPS'.
