I started sub, lingual b12 at the weekend andfeel even worse. Terrible bone and muscle pain and even worse lethargy than usual. I feel vacant that makes sense.
Does anyone know if there is a link between b12 and low potassium? My potassium was 3.8 in January before I started oral supplements then recently changed to lingual. I don't know the range I am afraid. Any ideasanyone??
