How frequently do you do the flushes?? You may still not have not fully recovered from the temporary elecrolyte and mineral imbalance caused by the liver flush. I experienced something similiar(minus the metal taste in my mouth) when I was doing Liver Flushes every two weeks. It was due to a folic acid, magnesium, potassium and iron deficiency. When I started doing flushes every month, the symptoms cleared up and the deficiencies went away. Lol, the flush may not only be flushing stones, but also important minerals with it. It is really important to greatly up your intake of vitamin and mineral dense foods(fruits, vegetables, etc., before, during, and after every flush) and to greatly up your intake of alkanizing minerals through such things as greens powder. It is equally important to give your body sufficient time to recover between flushes. Don't get carried away; a 2 week wait may not be sufficient recovery time between flushes. I know that this is the established protocol, but everyone is different. Just because two weeks is enough for one person does not mean it is enough for everyone. You may be better off to wait 1-2 months before your next flush to ensure that you are fully recovered.
