Is drinking sparkling water a healthy alternative?

My takeaway from the article is that sparkling water is mostly fine, with some minor pros and some minor cons. To me, the biggest one is that you're ingesting slightly acidic water which can erode your enamel over time, so you should be sure to monitor your teeth and get preventative checkups. I doubt, though, that over a lifetime anyone is likely to experience any serious side effect from consuming carbonated water.
To me the pros outweigh the cons. I feel more full (so I eat less), the taste is great, I enjoy burping up the excess Co2, and I'm getting a bunch of water into my system that I might not otherwise.
So recently I was overjoyed to find an appealing brand of sparkling water at the farmer's market, and I started ordering it by the case. It comes in great flavors, and it has nothing added to the water except "natural flavors".
My only fear is that I have no idea what is in those "natural flavors", because it literally could be anything. That is a key phrase used to hide ingredients and pull the wool over the consumer's eyes. It could be completely innocuous or it could be harmful. And I have become accustomed to drinking this sparkling water in large quantities throughout the day, so any significant or long-term effects will make themselves known soon enough.
Just saying "natural flavours" would never fly in my country, you'd have to list exactly what's in it.
Certainly symptoms like dry mucous membranes or lightheadedness can be caused by mechanisms other than dehydration, and it would surprise me if sparkling water could cause symptomatic dehydration (as opposed to correcting it, since the main ingredient is water).
I have no idea why so much sodium is present.
Some soda water is salty (maybe tonic), but in general it's either just carbonated, or it's carbonated and has a bunch of minerals in it (more expensive mineral water that might have calcium, potassium, etc. in it).
