Daniella,
So sad. Prevention of problems is discouraged. Of course, if you develop those problems then there are plenty of pharmaceuticals to take.
Regarding your B12 tests, I think I remember something about them. Wasn't the 2000 result after your getting B12 somehow but not stopping for a few days before the test? And wasn't the 1500 after having stopped a few days?
Forgive me if I am wrong.
