Does an all organic vegetarian diet help Fibromyalgia? What are other ways to cope with Fibro?

I have tried massage, chiro, physio and IMS (Intramuscular stimulation) it helps but only for about 5 days and its painful and expensive. So far IMS has been the best thing I have tried. I am about to try Prolotherapy an injection of sugar water and a numbing drug. I have also started on an all organic no meat diet.
