Thank you Rose, I had to force myself to go food shopping this morning. I actually broke down in tears in the car because I was that exhausted from shopping. I am going to call the hematologist now and tell them that I cannot wait and Iam going to start taking the b12. I bought by Biochem superior b12 methlcobalamin 3,000 mcg it also has 50mg of C and 400mcg of folic acid in it. Should I start taking just one tablet? (actually they say sublingual lozenges).
