Week 1 in the books of Juice Fast

So week one of the juice fast is in the books. I have dropped 8.5lbs and I feel really good except for one thing that will probably derail my 15 days goal. My mouth has this annoying awful dry taste of juice that won't go away. It is driving me nuts. I'm thinking once I hit 10 days which would be Monday morning to call it quits and get on with phase 2 of my diet. This taste is disgusting.
