Restlessly excited (8)
I believe the answer is:
feverish
'restlessly excited' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for feverish that I've seen before include "Frenzied" , "Restless with excitement or agitation - got ague?" , "hectic" , "Febrile" , "Restlessly excited" .)
