Bryon, the pain in your muscles may be caused by low minerals and loss of electrolytes. Make sure you get plenty of potassium, magnesium and calcium in your diet before your next flush, even adequate salt is very important. The day you flush and for a couple of days after, consider taking a supplement called EmergenC. It contains Vit. C and minerals and is excellent to use with a flush or any other time your reserves and energy get low. It is available in most health food stores and even at larger Walmarts and Walmart Neighborhood Markets (I just happen to buy mine there)and I would imagine many other places as well.
Repeated Liver Flushing has dramatically helped my allergy problems, although they are not completely cured. I now only have a few flare ups a year where my problem with molds and pollen used to be constant.
