yea, I recently found out about it as well.seltzer ruins the enamel on your teeth
(I just found that out, from a friend).
Sort of disappointing, since I like seltzer
But, oh, back to your goal thing. Well. Good luck with that and all...............
I knew seltzer is an acid, with half the ph of water,
but I guess I never put 2 and 2 together
