                        I was diagnosed with B12 deficient Anemia in the 1960's.  I took Vitamin B12 shots approx. 20 yrs. (In my case),  Now 35 yrs later I am fine.    Vitamin B12 did wonders for me.   Remember, every persons case is different.    I don't know what treatment is today for B12 efficiency.  Good Luck to you & your wife.  Bea
