Thanks for replying

I am gluten and dairy free and it has helped some issues.
I find the IM B12 much better than the sublingual... sadly!
I was not finding the sublingual of much use at all. I was getting it from LEF, which is supposed to be the good stuff. It is not yet available in Ozzy Land. Neither are the B12 patches, sadly.

Docs have this ONE SIZE fits mentallity, which is totally inaccurate for the human body.

I shall read the links you have suggested..... Thank You for writing. No doubt I will write more after reading.
