I drink a lot of tea, because I work on the phone, and would not be able to work most of winter otherwise. Seattle doesn't get really cold, but it is wet, which makes it wonderful for producing colds. And I still get cold, even if it hardly ever drops below freezing.
I also drink mochas and lattes and such... a lot of places around here offer soymilk (some even rice milk... yay!), which I've been been trying. I notice the soy-after-taste more in these, however.
Tea, though, is number one for me.
