I had some blood work done which shows slightly elevated B-12 levels.
Been taking a 1000mcg/daily since late July.
Apparently the normal range is 211-911 pg/dL. Mine was at 913.

My question is, should I follow the advice of this random internist (a doctor I saw once, and probably won't see again) to cut my dose to 500mcg/day?

She has zero expertise in head injury, my appt. with her was essentially just to order some lab work.

Is the B-12 doing a lot of good, and I should stay the course with 1000mcg?

Symptoms are better, teaching part time, but still have "jammed up" tension headache feeling the minute anything even mildly stressful occurs.

Also afraid to go off MagMind-- a supplement that I swear has helped me times a million (since taking this 3 weeks, my sleep problems are gone, feel calmer, less headaches, more "myself").
