Try drinking a couple more glasses a day (you can have as many as 12 and I wouldn't be concerned if you occasionaly drank more) and be sure you are getting enough water. Both will help with the cravings.
Also, drinking enough of the mixture and enough water will also help you loose weight, not hinder you.
What Hopsino said about the cleansing process is spot on; something the energy doesn't come as quickly, but when it does, it is SWEET!
