My mom use to make these once in a while if someone had a really bad cold (didn't matter their age).  It reallllllly helped us sleep, as they say, like a baby!  She usually used rum and brown sugar because we had that on hand for her baking around the holidays and sometimes a bottle of rum would last us for 2 or 3 years.  My parents just weren't really into drinking much.  But boy, I remember these babies . . . whooooo . . .
