Iam suppose to a wait another week or 2 before going for blood work for b12 serum. It is now almost 3 weeks form the first shot. I thought I did not feel any better from the shot but now I am think I was wrong. One week after the shot my vision started to get a little fuzzy. It has gotten to the point that it is interfering in work. Iam also getting that teribble tired feeling back and I feel dizzy alot. I had a parent teacher meeting tonight and really embarassed myself. I was stumbling over every word that came out of my mouth. I feel like nobody really gets it. I feel very much like Iam in an episode of the twilight zone.
