What type of diet are you on. It sounds like you have done a pretty thorough job of cleansing the liver. Have you done a colon cleanse. The best colon cleanser in my opinion is "Homozon" it is an ozonated colon cleanser so it adds oxygen to the body.
What type of dental issues do you have. Do you have root canals or other dental issues in your mouth. Are you on an alkaline diet? What percentage is raw. You should be taking a well balanced digestive enzyme supplement along with a good quality Alkaline Water source.
What type of diet have you been eating for the past 5 years. Do you eat a lot of meat and dairy. I would remove the dairy from your diet completely. I would also check out MSM/CS instead of the DE.
Also if you are going to brew the Essiac, it loses it's potency in a year to a year in a half unless it is vacuum wrapped in the freezer. The Sheep Sorrel herb needs to contain the roots of the plant also for maximum benefit.
I will look for a return message from you and see if I can help more once I know more of your answers...
