My B12 was low recently. I gave myself B12 injections weekly for 8 weeks. At the end of 8 weeks my B12 level was checked and it was normal (mid range). Now I am on monthly B12 shots for maintenence. I was tired for the few weeks, but I started MTX injections at the same time which could have caused the tiredness.
