Other?: I am sure that they have checked other things such as thyroid etc. Are you sleeping well? Post viral fatigue? Signs of depression? In other words many things can cause fatigue!

Other reasons?: For your tiredness there may be other reasons causing it . Did you have low B12 level before starting it. Anemia, nutritional deficiencies -not only B12 , but others -like malnutrition with poor eating habits, adrenal gland problems, chronic infections, anxiety with depression, thyroid gland problems, undiagnosed diabetes, and so may other causes can lead to tiredness. See your family doctor.
