No sodas here.
Tejava iced tea, and carbonated mineral water.
A regular soda is basically just a sugar bomb. I would prefer to use up my pancreas on a nice piece of chocolate.
Nutrasweet doesn't bother me, and I sometimes chew gum that has it, but it gives my wife headaches. The field of artificial sweeteners has broadened to the point that I would need to do research on it if I wanted to use them.
The last label I looked at had a "natural" sweetening chemical I'd never even heard of before. There seem to be dozens of these.
