B12 shots for anemia


I was diagnosed with a B12 deficiency about 5 years ago and have since been receiving injections every 12 weeks. I have always struggled with tiredness, and thought receiving the B12 injections would solve this. I am still feel very tired, often needing to go to bed straight after work and sleeping through the night. I rely on the weekends to catch up on sleep as well - meaning i don’t like to plan much on my days off.

Has anyone else experienced this? Could there be another reason for me being tired all the time?
