I have started a fast today. I cant at this present moment tell you how long it will be. I would like it to be 5 days. My only problem is that i quit when i am already half way through and i think with a whole lot support i will be okay. My problem is that i would consider myself overwieght, i also need to cut donw on eating junk food. the minute i see good food i go crazy in the head. My major problem though is that fact that i get headaches and aches every where in my body. When do these actually fade away. how many lb's is one expected to loose after 5 days of a water fast.
