A Simple solution for blood sugar imbalance will be to sip the orange juice slowly and also to water down the juice. Most juice fasts require that you water down the juice a little bit.
Also, I would deal with the parasites in some way first, either through the dewormer or clarkia. I always recommend cleaning the colon and kidney before cleansing out toxins, so that they have a way out of your body. There is no use detoxing your tissues, if it will recirculate back into your body. Castor Oil packs on the abdominal lymph nodes will also help.
Dr. Christopher's Pancreas herbs to strengthen the pancreas prior to a fruit juice fast of any kind, will be an excellent thing to do too. Thanks.
