Hi there Bryan-
I'm sorry to hear about your health issues. SPS is a member of the GAD65 antibody autoimmune disorders.(SPS, Myesthinia Gravis, Sjogren's, CIDP, etc...) Many of these disorders have overlapping symptoms. You also may have more than one disorder. There are tests to figure out which one you have and treatment is different for each. From the sounds of it, you have an autoimmune issue that involves your central nervous system. You need to find an auto immune Neurologist . These will generally be at the major University Hospitals. They will be able to determine what issue you have and treat you for it. I wish you the best!
