I recently had some Vitamin B12. I read on it and got valuable evidence to show it could help Ataxia. But when I took them, when the week came to an end: I felt more unsteady (off-balance); weaker muscles and weaker bones. Is this suppose to happen? I think it might be another mental issue. I've stopped taken them but because of the research on B12, I think it could help me. Someone please tell me whether I should continue to take them or disband them completely.
