I have found a medicine (courtesy of Matthew & Kristen's birthday gift to me) that tastes even worse than Robitussin:
It tastes like black licorice. And really, who wants that to be the taste that lingers in their mouth all night long?
ick! For all the effort it took not to gag while swallowing the 2 gallons (was it only two tablespoons? you could've fooled me!) I consumed, this stuff better work really well!
