When you say NM, is that New Mexico? I would strongly urge you to look into alternative ways to heal from lyme. Herbalist and naturopaths, lots of folks have used those to heal from lyme and many of these practioners are more knowledgeable about
supporting the entire body using supplements etc. to help your body get back to vitality.
Although I see your ND is treating you for CFS. I would just explain to them that you don't think it is the answer and given your posting it seems that you really haven't improved much. I would say find someone else.
