Hi Snowflowr82! I am on my ninth day of fasting today. And I am home! Yes! I was so exausted from working, I couldn't think straight yesterday at work. People started to tell me things, like "are your sick", "what's wrong with you" etc. I thought inside, Dr. Shelton would not have approved of fast with no rest plan. And your question was??? Just kidding. Like you I have a strong desire but not for food but just for a juice drink. I already imagine all the fruit juices I will drink after I end the fast. I want to do vegetable juices first though. You haven't had any headaches or nausea. That's great! I still feel nauseous from time to time and definitely weak when I stand up or walk. How does your tongue look? Is it white or pink? You know they say if you feel well and your tongue is not white any more that's the time to start eating. My tongue is still white. Let's not forget you are 12 years younger. Imagine how many toxic foods me and other people have eaten in 12 years. So, may be 7 days fast is enough for you especially if you weight is OK by now. I think it is very individual.
I don't know if Chrisb has already responded to your question. But he definitely could give you the best advice based on his experience and knowledge.
Good luck with you decision. Julia
