I just had to chime in here... I too agree with the previous poster in that your level is too low. My B12 deficiency was discovered with a level of 83 or 84... and after 5 injections (done approx 3-4 weeks apart) my level rose to 609... and at 609 I still have some symptoms! With a level as low as yours I would feel like absolute crap! Sorry.
I think if you doctor refuses to prescribe you any supplementation, you should pick up some over the counter yourself. Just ensure you supplement yourself to at least 1000mcg daily, as the body will only absorb a very small portion. And Methycobalamin is the type most readily used by the body, so you may want to ensure you purchase this type. And, if possible, try to find sublingual supplementation - you place this under your tongue and thats where it gets absorbed.
The thing about B12 is it is not known to be toxic. Therefore, you cannot overdose on it as you can with, say, iron.
And, in my opinion, I think you should get a second opinion... seek another doctors perspective. Any doctor who follows "normal" ranges, and does not take any other factors into consideration is not one I would want to see. And as stated previously, the range your doc is using is outdated.
