The whiskey (aka Jack Daniels), lemon, honey cough syrup recipe
Okay, for all you Google folks searching for this that keep landing here...

Mom's mix: one tablespoon whiskey, one tablespoon honey, one tablespoon lemon juice.
Mom's dosage amounts: for kids, one tablespoon of mix; adults drink the whole thing.

Ann's "I need to sleep" recipe: one ounce whiskey, 1/2 ounce lemon juice, one tablespoon honey. Optional: zap it in the microwave. Adults only, drink it all. Repeat every hour or so until you finally conk out. Within reason here; if you've got a really bad cough and this doesn't help after a few hours then you probably need to go see a doctor.
