Seltzer Water, etc.
Thanks everyone for your responses. So, tonic is out but soda water
is fine. I know that sparkling mineral water has less carbonation
but is it still okay? There’s no sweetener in it. I like dilluting
my juice with it too 
My favorite is a splash of unsweetened
cranberry juice (very high pucker factor) a splash of pineapple juice
and about 8oz sparkling water… Excuse me, I ramble. I’ll try to
find out if sparkling mineral water is okay, but if someone finds out
before me, please post.
Thanks,
Eva
