Found a can of cub soda that when opened it fizzed nicely. Plastic lime juice, vodka.

I've used the plastic lime with decent results, but Club Soda needs to be fresh & this stuff didn't get it.

Back to the red Gator Aide & it still works. Know it has ingredients I don't need. Still would like to find a quick, clean & refreshing, easy mixer for vodka without so many additives.
