I can't offer any dairy advice but I do have some water input. I am serious water drinker. Even before starting this WOE I was drinking almost a gallon of water a day. I have found that bottled water tastes better (yes water definitely has taste). I don't know what brands you have available but some of the offerings here include water that truly has nothing in it. There is a debate about removing the good minerals with the bad things but I just know it tastes better. I also know that studies have said that most bottle water is no better (and in a few instances worse) than tap water. Personally, since nothing is labled and testing your tap water on a regular basis would prove troublesome, I would say follow your tastebuds. I think we have to be careful not to find excuses not to drink water.

For what it's worth.....
