'sustenance in the morning?' is the definition.
'breakfast' can be an answer for 'sustenance' (breakfast is a kind of sustenance). I am not sure about the 'in the morning?' bit.

'tabs freak chewed' is the wordplay.
'chewed' indicates an anagram.
'tabs'+'freak'='tabsfreak'
'tabsfreak' with letters rearranged gives 'BREAKFAST'.

'for' is the link.
