Congratulations outattheblue. Some things that help juice fasting- get a twin gear juicer. I got an expensive Breville 800 JEXL juicer that's almost the same price as the Green power kempo i got but the kempo crushes the fruit instead of cutting it, extracts more juice from fruits and vegetables and i went from needing to drink 8 cups of juice a day with the Breville to only 4 cups a day with the Kempo! Save money! Also an important thing is to get in your greens- it will help you juice fast longer- no matter how you like to get it in- i personally hate green juice and i've tried many different concoctions so i usually eat the greens in a fat free salad.
thirdly, the water should be ph alkaline and ionized AT LEAST. There's an energized water forum that teaches you how to ionize your water for very cheap or you can go my route and get an expensive Jupiter Melody ionizer (it does a lot more things) and to alkalize the water you can purchase alkalife drops for $30. so, to start with the water all you need is like $40-$50 to start! And the water will make Water Fasting a lot more comfortable. Try it!
