Thanks, I know b-right was taking off the protocol but I still have 1/2 a bottle so I thought I would just finish it. I don't think I have a problem with folic acid. I have been trying to figure this b12 thing out for long years now. To honest the only vit/sup. that I have taken that made a difference or that I could actually feel a difference was Jarrow's methly. I know that is not on the protocol anymore either, I think. I take b fusion now. I just had two iron fusions so my iron is up but I still get sooooo tired and the muscles in my thighs still get the feeling that the blood has been drained out of them everytime I walk up a flight of staris. I am about to give up and just live with the fatigue.
