U know, Queenie, that back pain can be an indicator of a gall bladder issue (has someone already said this??). Anyway, you might want to try a liver/gall bladder flush in a coupld of weeks. And don't forget the parasite cleanse the week prior (you don't have to be fasting in preparation for these).
God bless and take care of yourself!
P.S. My nephew is a vegetarian (has been for the majority of his 23-yr. young life), but he weighs about 310 pounds and is, I'm sure, extremely toxic. It isn't just meat and dairy that do it to ya... :^)
