Oh Nigel, where can the IQ have gone?
Symptoms of Vitamin B12 Deficiency
mental fogginess problems with your memory mood swings lack of motivation feelings of apathy fatigue and a lack energy muscle weakness tingling in your extremities
One of the most important functions of vitamin B12 is building the myelin, which insulates and protects your nerve endings, and allows them to communicate well
my my Nige, maybe a really big dose of, dare I say, B-12 Vegemite...... just may help you replenish your myelin
