<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">avoiding alcohol</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for teetotal that I've seen before include "Abstaining completely from alcoholic drinks" , "Abstaining completely from alcohol" , "Avoiding alcohol" , "Completely abstinent" , "On the wagon" .)
