I've done a lot of fasting through a lot of periods. It's an excellent time to help your body detox, as it is naturally in a cleansing mode at that time.
Hang with it! It will definitely help you regain your balance.
Another excellent idea for you would be a liver flush. Go to the great Liver Flush Forum here at curezone and read up--the liver is responsible for hormone production and cleansing it can really help get things back on track! It may take several flushes (it took me about five before I passed a whole BUNCH of stones), but the results are WELL worth the patience! You can do a Liver Flush about every two weeks. Again, go to the forum and read up, ask questions...
