It seems to me that the NHS treatment I am getting is aimed at keeping me out of B12 deficiency, not about giving me the optimum level for health. So in the long term it could be a good idea to bump the levels up a bit more.
I know a lot of people self-inject but I am looking into alternatives to that.
I was wondering if anyone who has tried sub-lingual tablets or sprays has found these effective? I suspect this is very much in the territory of 'what works for one won't necessarily work for another' so I may need to experiment for myself once I am past the 'loading dose' stage, but I would appreciate the opportunity to learn from other people's experience.
