I believe the answer is:

vacillates

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

'is unsteady' is the definition.
I can't judge whether this defines the answer.

'quits sick inside' is the wordplay.
'quits' becomes 'vacates' (vacating is a kind of quitting).
'sick' becomes 'ill' (synonyms).
'inside' means one lot of letters goes inside another.
'vacates' placed around 'ill' is 'VACILLATES'.

'and' is the link.
