I had to fight to get a loading dose of B12 after being diagnosed as deficient. I was told to come back in 12 weeks for my first "booster". I didn't push my luck and ask to be tested for PA as I figured the treatment is the same either way but I suspect that's the cause of the deficiency as my diet is rich in B12 and I have had Hashimotos for 30 years.
2 months after my last loading dose injection I slowly started getting headaches and feeling abnormally tired again. I spoke to a GP over the phone after writing my symptoms down in an on line form. I suggested I might need an earlier top up of my b12 and he told me if that's what I wanted I'd have to go private! The headaches and exhaustion were my most problematic symptoms at diagnosis but they went away once my treatment started so I'm certain that must be the cause. I can't live like this for one month out of every three! If anyone has any advice I'd be very grateful.
Thanks for advice, I now need some more!
What dosing do I ask for when loading stops?
Completed loading injections, now what? 
Well what do you think
