why are you drinking that much water? Sounds like you're forcing it down.
It's quite normal to want less and less on the WF. I'm on day 11 (in another post I said eight, but that's a mistake)and finding I want less and less water. It actually feels like an intrusion.Hower, I am experiencing some heartburn -which I almost never get; didn't even know what it was, until someone else mentioned it and it sounded similar. The burning feeling feels like a blockage at the bottom of the throat, a bit like the feeling of having bread get stuck on the way down, at the same time as making me feel very empty (gotta love a paradox) and sometimes drinking water helps it subside.
