My mum has been telling me for years that she thinks I'm vitamin B12 deficient (I've been veggie for 31 years) and I did the classic 'I'm a grown up, I'm not listening to my mum' thing. Then last week I looked up the symptoms and I had about half of them. Some quite scary ones like palpitations, shortness of breath, tingly hands, aching legs etc. Anyway, one week later after finally giving in and taking the tablets and I feel AMAZING. I reckon I feel about 10 years younger. I have more energy, all the symptoms have gone and to be honest I feel a bit stupid that I ignored her for ooooh, about 20 years! AIBU to think that one week can really make such a difference?
