I myself have had something partially similar happen to me. I wasnt very hungry about a month ago so I decided that my body was communicating with me not to eat... After a few days of this, I began eating again (raw food) and my body completely rejected the food. Of course I didnt know what was going on because I had never read anything regarding fasting. I went to doctors and had tests done and the doctors put me on crazy diets and told me scary things. I read some fasting books (the best thing to do if you are confused) and now I know that this is a common accurance if you break your fast too quickly. Every book I read says that the breaking of the fast is MORE important than the actual fast.
