I have never water fasted and started the Fuhrman 6 Wk Plan last week. It is basically a vegan diet - until you have lost the desired weight, although there is room for flexibility in his plan.
I lost 5 lbs. the first week. The best part is that I have no cravings for meat, cheese, butter, eggs or sweets. I am very satisfied and feel great - lots of energy, skin looks terrific.
If you are interested, Roooth and I are both keeping people posted on this forum. (I believe Roooth does have some Water Fasting experience.)
