Fizzy drink will briefly give you zip (3,3)

Ross

I believe the answer is:

sod all

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

'briefly give you zip' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'fizzy drink will' is the wordplay.
'fizzy drink' becomes 'soda' (I've seen this before).
'will' becomes 'll'.
'soda'+'ll'='SOD ALL'

Can you help me to learn more?

(Other definitions for sod all that I've seen before include "duck, perhaps?" , "nothing" .)

I've seen this clue in The Independent.
