>>14230913I'm a waterfag, but if you sodafags absolutely need sweet flavouring in your rehydration then the zero sodas are the best option. Any sugar, even 100% natural juice is way worse for you to consume regularly compared to the artificials.
However, probably what you are really looking for is an occasional salt/remineralisation tablet with your water. Sweet flavouring in water is a bad substitute, once you give your body what it actually needs you will never buy any kind of soda ever again.
