<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tonic</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that pick-me-up is a type of tonic)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for pick-me-up that I've seen before include "Stimulating drink" , "A restorative tonic drink" , "A tonic to restore health or relieve depression" , "Stimulative drink" , "Medicinal tonic" .)
