i actually used to suffer from chronic migraines. i used to get them on average about every other week and they would be pretty bad: impaired vision, vomiting, numbness in my extremities (usually affected one side of my body at a time. happened to my face once, and it was really weird. even one side of my tongue went numb.) anyway, after medication refused to work my dr. gave me a brochure listing possible causes of migraines. all sorts of things were on the list from chocolate to cigarette smoke and lack of sleep. one of them was processed meats, and that was the second or third thing i tried cutting out of my diet, and after about a month i noticed an improvement. i still get them every few months or so, but the amount of decrease really made me wonder what kind of additives and steroids are in the meat sold to market these days.
