re: Would ya'll consider half pint of whiskey a night unhealthy?

Sure if you want to go down that route, anything that's not perfect for your body can be construed as unhealthy. Which is probably the majority of foods in the American diet.

I think the premise of this thread is will it cause chronic negative effects on your overall health.

Which I don't think "any" amount of alcohol everyday will do for an otherwise healthy person.
