I've never had a problem with my water, in fact I've been tested for diabetes because I drink so much. 5-6 750ml bottles each day at work plus 4-5 cups of herbal tea, then another 2 litres of soda water with a squeeze of lemon or lime juice at home... I think I down about 7L a day.
myself I am trying to limit the diet coke and drink more water, trying for 1L of water daily how about everyone else?
