Hot sauce, I love heat! I haven't tried it in water or club soda. Will try it.
The artificial sweeteners are neurotoxic. Possibly cancer inducing. That being said, I enjoy a glass or two once a month. Moderation. As gymdandee said, water with lemon is a good option. Try adding a drop or two of hot sauce to the drink. All of the soft drinks have problems.
It's not good! No coke, Pepsi, or any others are good. Try club soda with a slice of lemon or water with lemon.
