Translation of "goitika" into English

Zuk ez dakizu merkurio gustua sentitzen dela ahoan kirofanoko ohatilan etzanda, goitika egiteko gogoa ematen duela; goitika ari deneko mugimendu hori egiten duela tripak, zabal-zabalik, hesteak eta gibela eta behazuna bota beharrean.

You don't know that you feel the taste of mercury in your mouth while lying on the operating table, that it makes you want to throw up; that your stomach makes that movement of throwing up, wide open, instead of throwing up the intestines and liver and gallbladder.
