I switched to goats' milk, and I only use that for coffee, so I go through about one quart a week It tastes just as good as cow milk, and is heathier. In fact, goat milk is consumed by more people in the world than cows'. It's more expensive.

I also use Vances DariFree, which is a milk substitute made from potao. It's fat fee, cholesterol, lactose and gluten free, and an all-around better choice than dairy - and cheaper, too.
