Whilst I drink plenty of water during the day I like to have a glass of Tonic water or Soda water in the evening, reading the labels these are pretty plain drinks with only traces of stuff in them but basically void of calories. Am I right in presuming these drinks are not doing me any harm as an alternative to plain water?

This may sound stupid but better to be safe than sorry!

yea, i use these to trick myself into getting my pop fix. i take cranberry juice and mix it with soda pop .... has the texture of pop (what i'm really craving) and is all good for ya.

usually they have some sodium. if its a lot of sodium, have an extra glass of water to offset it.

I have never seen any tonic water with anything it is... it is just carbonated water... drink away...

Put a lime in it and... (yeah some added natural sugar) but wow that tastes great.
