Hi, 2 years ago cfs was something i was diagnosed with along with other things, b12 deficiency being one, after 6 months of monthly injections i was changed to 3 monthly. My b12 measured 1400 a week after my injection, 3 months later i was at 200. My symptoms are worse then ever. My doctor doesnt see a problem and says it nutritional. Im 'leaking' b12. This cant be normal, my research points me towards pernicious anaemia and on other thread i have read about promising treatments. Anyone else have these sorts of numbers? Sorry if its all been done before, just need to start somewhere
