Little tablet you got me (6)
I believe the answer is:
touche
'you got me' is the definition.
('touche' is said to acknowledge a fair point)
'little tablet' is the wordplay.
'little' becomes 'touch' (eg 'a little too big' means 'a touch too big').
'tablet' becomes 'e' (E can mean ecstasy or an ecstasy tablet).
'touch'+'e'='TOUCHE'
(Other definitions for touche that I've seen before include "Fencer's shout" , "cry from fencer" , "Acknowledgement of fencing hit or valid criticism" , "Acknowledgement of a good point" , "That hit home" .)
