Newbie with a soda alternative

Hi all.

I have just switched from my beloved diet coke with all of its sodium to diet rite pure zero.  It has 0 calories, 0 fat, 0 sodium, 0 carbs, 0 protein, 0 caffeine.  It is made with splenda.  It also doesnt contain aspertame. 

I know water would be a better choice but is this a good choice for my carbonated habit?

Do you like seltzer?  They have rasperry, lime, cherry, orange flavors and it has no artificial sweetners or anything.

I think walmart has these but I thought they had sodium and nutrasweet.

Ill have to check it out thanks.

That is the only diet soda I have found with zero sodium.
