I too only like my water really cold. I freeze water in my Polar water bottle to take to work. The ice lasts most of the day in my classroom. The fake sugars give me a headache. My MIL uses them in her cooking and I had to ask her to stop.

At home I do what Darcy does - mix water and either lemonade or OJ. I tend to go about half and half though.

I do not mix my Red Bulls with anything though.
