Mention me going west, inducing sickness (6)
I believe the answer is:
emetic
'inducing sickness' is the definition.
(I've seen this before)
'mention me going west' is the wordplay.
'mention' becomes 'cite' (to cite is to mention or quote).
'going west' is a reversal indicator (letters heading to the west or left).
'cite'+'me'='citeme'
'citeme' backwards is 'EMETIC'.
(Other definitions for emetic that I've seen before include "Purgative" , "It makes one sick" , "It would make you sick" , "Ipecac is one" , "Vomiting inducer" .)
