The amount of B12 absorbed orally is so small. I don't see how you could be having these extra symptoms.

I'd see a doctor and make sure you don't have some other problem. Get an EKG, and a complete check up.
There is a blood test that checks for antibodies to parietal cells in the stomach, which make intrinsic factor.

Also get checked for H. pylori infection. This can give all sorts of weird symptoms.

Seeing a doctor is a good idea at this point.

I am also not certain, however I seem to react excessively to all medications, but I assumed this was due to the B12 deficiency itself. Hopefully there is not another serious problem.

Thank you, I will definitely do so. An infection from parasites does seem likely, although possible dietary deficiencies from a horrid past diet can be to blame, as well--E, A, calcium, iron, omega-3, DHA, magnesium, zinc, D, selenium just to name a few.

nerve dont read into any of the jazz that dr. oz likes to spin on his show, about glass feelings.

Have you taken klonopin before? I took klonopin and for awhile i was having problems with loud noises. That was the link. also i took mullein before, and that seemed to cause a fluctuation in noise?- is that the problem?

Also, at one point i was taking ssri antidepressant, and that caused weird symptoms like the glass thing you described.

also betaine, i cant even stomach the stuff. maybe my pill size is too big. but it feels like a lump when i use it, is it more helpful to use it more often?

I only say this because Dr. Oz sometimes has vivid descriptions of things that people might have, and if say that information was given to the wrong person(ie someone who is already a hypochondriac) it can prove costly.
