B-1 (Thiamine) converts carbs into energy and I know it is important to the nervous system, heart and probably muscles. No wonder you feel better. That might be worth a try here. I am fatigued and sleeping so much, you wouldn't believe it...

Why is B12 so expensive in Australia? Is it considered a prescription med? Can you not order it online?

Guess I need to rethink more on the supplements and vitamins... I will have to look for MrsD's list.
