Hi dcd2103, I don't have any fillings so that part should be o.k the big reason for the alpha lipoic acid right now is the oral burning I am having and read a few places it may help but I guess at this point desperation on my mind as it is painful. All my liver functions etc. are normal, It being autoimmune I would think hep c would have fallen into that area,but now cleared. Right now I am seeing a new neurologist so I will go over these types of full work ups with them.
