I've been trying the new (to me, anyway) Halls ProHealth Defense tabs. They come in a 18-dop box and each drop is only 15 calories. It comes in blueberry or citrus-pomegranate and both are pretty tasty. I also have been trying to eat even more vitamin-rich vegetables and foods to ward off what seems to be a constant cold threat. Even though I have been sick more this year than I have in a long time, my colds and sicknesses seem to be shorter and less severe than what I've seen other people going through.
What about you? What have you been doing to stay healthy?
