thanks, cara and linn, for your responses. i really appreciate your taking the time to share your experiences with me.

cara: you know, you're the reason i had my b12 level checked. i found your story online about a month ago and it sounded so much like my situation, and it gave me hope for a solution. needless to say, i was pretty disappointed when i got the results that my b12 level was 900. i cried my eyes out.

after thinking about it more, i realized i wasn't fasting, and my dr. said that didn't make a difference; however, after doing additional research, i found out that it might. i have been taking 5000 mg of b12 here and there, but i think i will try to take it more regularly. some days it seems like it makes me feel better, but i don't know if it's a placebo effect or not. my MMA result was 153 with the range being 87-318. i don't know really know what that means since my dr. said my results were normal and haven't found much information about it online.

i have not been checked for lyme disease or celiac disease/gluten sensitivity. i was actually planning on discussing lyme with my neurologist during our next appointment, but what kind of doctor would i see to have gluten sensitivity identified?

linn: since posting the first time, i recently had a visual evoked potentials test to further rule out MS. my results were normal and now my neurologist says MS is off his radar. if i don't get any resolution soon, i just may look into going to the mayo clinic. i looked at their web site and they take my insurance, so there really isn't any reason not to pursue it.

thank you again,
