Suggest Treatment For Firbromyalgia

I m female,51, 5 7 148lbs. I am fairly healthy. in feburary 2011 my hands and feet started tingling. My Dr. has done blood work, MRI of brain and neck. Thyroid and sugar levels are fine, Vitamin D level low, I am taking Vitamin D 50,000 once a week for 8 weeks so far no change. I started taking supplements , B12 has helped some along with Alpfa lipoic acid. Changed my diet and exercise. I refused to believe I have fibro, My Dr presrcibed Xanax to help with anxiety caused. It helps calm my tingling down at the end of the day when it seems to be it s worse. My hands are always cold, I can t hold cold drinks in my left hand. I take 100mg celebrex for mild carpal tunnel. I do have two bulging disc but neurologist says it would not effect my feet, Im thinking about starting Barley green. Any advice you can give me would be great. Thanks I have seen a neurologist. he says firbromalgia.
