I will post the B12 levels when I can locate them. I have a huge folder of all of my medical records. Mayo called me today and instead of waiting until October they're getting me in on 8/20 now which is really nice. They are going to repeat the single fiber EMG and look into some other things that may contribute to my problems. Last time, I didn't have an abnormal test but I really believe this is going to come back positive because my entire body is weak at times and my muscles strain/tremble if I over do it. This goes away with rest. I've upped my Mestinon does and I have seen improvement with my energy level, but it doesn't touch the vision and all of the weakness. I guess at 27, if this is the MG kicking my butt and making my eyes off constantly, I'm worried about progression/recovery. I'll have to see what they say.
