Now apart from the aspartamine in regular drinks brands, which all say 'less sugar', which means more aspartamine, then you get the Benzoates. http://www.feingold.org/PF/benzoates.html
Now heres a nice picture of what has to happen to break down these little monsters.
This is why I only drink flavorings for water from natural things like lemon and mint, or blackberry cordial which keeps fine as ice cubes in the freezer. My Mum told me never to drink water with a meal. For one hour before or one hour after. We could have milky tea though.
So just in case anyone is wondering why everyone is getting sick, just cut out all bought drinks, fizzy especially. Funny, Beers and Wines if they are traditionally brewed are very beneficial I like a can of IPA myself!
Right that's me, I am off to watch some telly, Have sweet dreams everyone.
