Mary:

I know your question was to Brian, but I just wanted to share my own info on the B-12. I take 5000 mgs sub-lingually every morning, on an empty stomach.

It did the trick. I'm one of the lucky ones. It did nothing for my husband but he's not a diabetic, and in my opinion, he wasn't on it long enough to say "oh this is not working, you take it". But I can't argue with him. So I take it and it does the trick for me.

Sure, I get flare-ups but only when I get stressed. On the average, it did the trick for my burning.
