I recently started drinking the healthy meal shakes (not the diet shakes) from Herbalife and have noticed a feeling of shakiness, weakness in legs and anxiety. The label says it contains dietary fibers, could this be in the form of an artificial sweetener such as aspertame, etc? Or could it have an ingredient for weight loss that would cause me to have these symptons? I have called the company and they give me no information at all. Also, my BUN count was elevated at last blood draw and am wondering if this is due to the protein in them as I never had this problem before. Anyone have any answers? Thanks
