It is soo true about artificial sweetners. I used to be a huge diet pepsi drinker then one of my co-workers sent me an e-mail about a true story of a women who was on her death bed because of an overload of artificial sweetners she was consuming. So I decided for an experiment to go off all soda and anything with splenda or aspartaine for a week. Now 2 weeks later I feel a huge improvement. Im not getting that achy joint feeling anymore and I find I have way more energy then I did. My arm used to get soo tired from brushing my teeth now it hardly ever bothers me. All of my "lupus" type symptoms have pretty much gone away..so it makes me wonder, as much of a strech it is but could some of these chemicls actually cause a person to have a false ANA positive??? Has anyone heard anything like that before???
