Thank you, Sally.

This experience with this has been pure hell on earth for me, that and having had an adverse reaction to antidepressants and now withdrawal from them. My vitamin D is low, too. I'm supplementing that as well. I'm only 30 years old, too. I feel like a worn-out 75 year old man.

I really hope my conditions improve over the next year or so. I just worry I'm not getting enough B12 or that I'm not doing it right, etc. Everyone seems to do or say something different about how to get it. One doc said once-a-month shots were good enough, another says once a week then once a month. The method of taking oral (oral vs. sublingual) seems debatable, too. With all this debate, it just heightens my anxiety (which is already high from the antidepressant issues) as to whether I'm getting enough or am doing it right.

This might be a good question for MrsD - I have actually found a couple studies online that were done with the question of sublingual versus oral, and it seems that sublingual didn't make a difference in serum cobalamin levels versus high-dose oral just swallowed. I can't think of the studies off the top of my head, though. Maybe I can find them to share.

I am also giving myself a shot of methylb12, 1 mg, once a week for the next 9 weeks just to complete the shot series. It makes me feel better to just finish them off. That way I will have had 20 shots (or thereabouts) total, which should be more than enough to replete the liver. And on days I don't take the shots I will take the oral 5000 mcg.

Thanks again, Sally, for your advice!
