I used to hate water flavor, but i read that anything like coffee, tea, or mineral are not as good as plain, natural water.
I have one bottle of water in my desk at work, another next to my bed and one mother in the living room, always filled.
When you see those, you know you have to drink it, at the begining you have to drink as much as you can, but then you get use to the taste.
And believe me, you'll see the results very fast
