Yes it works for myself I try only to have the max/of two cups of tea and two cups of coffee in any 24hours but I drink a lot of bottle water and even take one to bed but most days I will have less hot drinks.
I find water much better and your body likes it to, keeps all your inside tubes etc nice and clean and clear and this will make you feel better.I do not drink any kind of beer or wine and has been like that for over 20years.
So stop that and smoking for a better and longer life.
