What the stomach did as one suffered after a drink? (7)

I believe the answer is:
rumbled
'what the stomach did' is the definition.
I can't judge whether this defines the answer.
'one suffered after a drink?' is the wordplay.
'one suffered' becomes 'bled' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' is a charade indicator (letters next to each other).
'a drink?' becomes 'rum' (rum is a kind of drink).
'bled' put after 'rum' is 'RUMBLED'.
'as' is the link.
Can you help me to learn more?
(Another definition for rumbled that I've seen is " Saw through - what the thunder did".)
