Calorie-free beverage options

[Wolfram]

I've been drinking diet-soda in very large quantities (1-2 liters a day) for the last 10 years.

If there are any health risks involved I'm pretty sure I'll be one of the first victims.

So far, I'm not that worried.

I used to make my own zero cal Italian sodas... Ice, 8 oz Club Soda (make sure it's 0 calories, some have sugar) and Sugar Free Syrups (DaVinci is good, Torani is passable). Cremosas are even better, but have cals(same recipe+couple Tbsp Half and Half).

Now I just drink Water and (home-made) Americanos.
