Dear Gina, RN The causes of fibromyalgia lie basically in the foods and beverages you are consuming. With food, you won't feel the effects until 2 to 4 days after ingestion (No problem with digestion. Problems come when body is trying very hard to metabolize or rid your tissues and organs of unacceptable substances.) Therefore, if you want to cure your fibro naturally (and also improve your overall health) you must meticulously avoid the noxious substances. Began to read all ingredient labels. Try this for four weeks. NO crystalline HFCS, no high fructose corn syrup, no HFCS. NONE!!! Also, avoid MSG. Works wonderfully for me, and I suffered and was baffled and perplexed for nearly 30 years. I now have twice the energy, do not suffer with fatigue, have very little pain, and take no medications. Remember a part of High Fructose Corn Syrup is a serious, nearly poisonous problem for the metabolism of those of us with Fibromyalgia. Good luck and good health.
