Need Encouragement!!!

I have been on a juice fast for 5 days. I am very lethargic, have a total loss of appetite and very foggy in thinking. This is my first juice fast and I really want to complete it but if my body continues to feel this way, I don't know if I can. I have not found a great recipe for juicing yet - they all seem to taste so leafy. I get the juice down but it has become an absolute horrible experience! I have 25 more days to go and would appreciate any help getting through this!
