Does anyone out there have Fibromyalgia?

Does anyone have Fibromyalgia or know anyone with it? I have it and cannot take pain medications as I am allergic to them. Does anyone know any alternative treatments I can try? Do you find that your pain goes in cycles? Do any of you experience a burning sensation anywhere? I have it in my back and chest and stomach and don't know yet how to deal with it. I also get VERY tired dealing with this pain all the time. Any suggestions?
