These are the only things I could dig up, on this subject.

That hepatitis c can cause a condition called Glossitis -which is a sore tongue. If you have glossitis, your tongue will be redder than usual and will be sensitive to salty and sour foods, and carbonated beverages.

And I came across something that said to avoid carbonated beverages and other foods that cause gas (like broccoli and cabbage) because they can attribute to loss of appetite.

There's also a study that was done that drinking carbonated colas lower bone density in women and attribute to osteoporosis, but the study didn't look into non-cola carbonated beverages so they don't know if that (carbonated water) will apply too and they didn't study men.

I've been told before the carbonation slows down the the absorption of fluids and can help cause dehydration, but I couldn't find any links talking about that right now.

WOW thank you so much, i could not think of where to go! i've been hooked on this water stuff for years, i can down a 12 pack in no time and i'm the only person i know who likes it so it's hard to find but easy to keep on hand..lolbut ya might just know it would not be the best thing in the world to do

I like mineral water myself wich is usually carbonated.

Im not sure but I add a little juce to my water

Maybe the key here is moderation. A carbonated bev once in a while is probably okay but water is best when drinking for hydration. Have a great weekend.

i found that carbonated water the no sodium type help with thirst and made my throat and tongue feel better

mimi, your responding to an antiquated post. ds is about as business savvy as toyota. make the easy buck saps, your product is trashed..way to bellyflop..

I disagree...nothing is beneficial. Soda water or say carbonated water is extremely harmful for your health. Beverages with a high sugar content, such as lemonade, increase the risk of numerous diseases such as diabetes , the metabolic syndrome , cardiovascular complaints and of course overweight .

A US study from 2013 showed that up to 180,000 deaths could be attributed to the excessive consumption of sugary drinks worldwide.

With 133,000, most of them succumb to the effects of diabetes. 44,000 people die from cardio-vascular diseases caused by sugary drinks, 6,000 from softdrink-related cancer .

This study, however, only evaluated the data from adults - the harmful influence of Limonade & Co. on children is not even taken into account here. You may read in detail at here :-http://mouthwash-oral-hygiene.blogspot.com/2017/02/side-effects-of-carbonated-water-soft.html
