Re: What didn't you know until recently?
Apparently I'm super-deficient in vitamin B12. The ideal is somewhere between 250 and 550 pmol/l and my test came back at 127. The at home blood test people have recommended I see my doctor about it.
Interestingly, the symptoms of B12 deficiency are all things I complain about regularly: dizziness, tiredness, mouth ulcers... It'll be a bit good if addressing it gets rid of some of that.
