I start my day with a cup of coffee and then it's water all day long.
I add just a splash of cranberry juice to give it a little flavor. My kids call it red water...it doesn't have much flavor, but enough for me.
During the hot days, I'll add some lemon slices.
lately I start with coffee, move onto water, sometimes have homemade chai tea that hubby makes, and end with a rum and coke or possibly club soda depending on my day. So I don't really have a drink of choice, unless I'm on a cruise, and then it's a Dark and Stormy!
