Felt dizzy (6)
I believe the answer is:
reeled
'felt dizzy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for reeled that I've seen before include "Staggered - having done Irish dance?" , "Staggered or tottered" , "Staggered around as if drunk" , "Felt giddy or bewildered" , "Staggered (at a Highland ball?)" .)
