I have been following this group for some time now and have learned a lot. I am in southeast Kansas , near McCune, and raise Nubian goats. several breeds of chickens, Guineas, African geese, and Great Pyrenees . I thought I would jump in on the subject of Lupus as My wife has this and was diagnosed in the 1990's. Her doctors told here it was caused by years of drinking diet soft drinks that contained Aspartame and using sweeteners containing Aspartame. I just received an article on this subject on my Facebook today on this subject. If I knew how I would post it for you to read. If you are prone to migraine headaches and drink diet drinks and use sweeteners containing Aspartame you might want to stop. Also it is believed to be the cause of the "Gulf War Syndrome". Aspartame converts to Formaldehyde when exposed to temperatures above 86 degrees F. The Gulf War Syndrome has the same symptoms as Formaldehyde Poisoning. a lot of diet drinks were exposed to 100+ degrees in the Gulf area. Well, enough on that subject. Have a good day. Ralph
