Yes, I was diagnosed with fibro/chronic fatigue over 15 yrs ago. I maintain and keep them under control by watching the food additives. Look up www.truthinlabeling.com and read what they say. I found my symptoms are bad when I ingest MSG and Aspertame too much. A little for me is okay, too much and I'm sick. It may be other additives are bothering you....do an anaysis of EVERYTHING you eat...who knows, you may end up being well again -- I am!!
