It seems to just be the B12. Not sure why just the 12 and not the 6 or other ones. Weird. Regardless, I've got to find something because I think the deficiency is what has been causing my dizziness, heart palps, motion sickness, etc., along with my neck. Had my eyes checked out and they are fine. No ear problems, except I have had tinnitus for years, but new doctor says that's from my neck problems.
