I don't know how much this lack of energy is from pernicious anemia. Besides the shots I am also taking 4000 m a day but they aren't sublingual. I read in a research article it doesn't matter but who knows. I am also probably not getting more than two hours of sleep in a row. That isn't helping. I usually lurk. I too am worried about BJ. She has gone through so much. I wish there were fairy wands which could heal us all! and we wouldn't have to do much work. lol I don't know about you but i feel once again that I am starting out from the beginning again.
