Has anyone had a problem with getting to much B12. My count was down to 258 so doctor started me on B12 shots right away. First shot took me to 425. Second shot a month later took me to 878. Don't what third shot to me to but couldn't stand up for three days because of being so dizzy. Doctor took me off all shots for two months and now has be on a half of shot ever month. Has anyone had this happen to them? Also, when I don't seem to sleep like last night I get the diaherra and feel awful. All most like stomach flu. Gas is a big problem too. When I take a diaherra pill it will stop and than when I finally go it starts my hemroids bleeding. It seem like a vicious cycle. Any one in the same boat as me? When will I feel normal again? Had to leave my job because of this. Found Activia helps with the gas. Can't eat a lot of foods.
