i understand..its not exactly easy finding a competent doctor. mine told me that with my low b12 levels it wouldnt be wise to take supplements because they dont absorb as well as injections and consequently it takes much longer for the b12 levels to go up. so what i did was a number of shots for a few months followed by supplements..are you looking for a second opinion? i switched doctors a lot..cant say i found my ideal one yet ) wish you all the best!!
