I have been following this post as well as other ones very closely.
All I can say is that you shouldn't stop drinking water. In my own fasts, I have noticed that when I hit a certain part of my fast like day 12 or 13, my water intake is cut down. I would be drinking up to a liter and half a day to bearly drinking 20 oz. Then I get like that I push myself to drink even thought I don't feel like drinking because I know I need to keep flushing my body, because my body is burning fat and it is trying to release itself out of my body. If I stop drinking water, the flush process stops and toxins can build up and make you feel very very ill.
I would suggest to keep drinking to drink a bit of water and not completely stop drinking it.
But I also know, regardless what anyone might advises you, you will need to make your own decision.
