I'm almost at the end of my loading dose (I've had 7 out of 8 injections over 4 weeks) and not have felt much improvement. I've had a slight improvement in strength levels, but nothing in the way of energy. After my last injection later this week, I'm being moved to the three-month regime.
I keep thinking about buying supplements to see if that will improve things any faster, but I don't know if I simply need to give the injections more time to work. It doesn't help that I'm also hypothyroid (diagnosed at the same time as B12 deficiency) and have no way of knowing how much of my continuing exhaustion is due to the fact I've been on 50mg thyroxine for only three and a half weeks.
I keep going round the circle of "Well, I can't overdose on B12, so what harm would it do to get some sublinguals", and "Would I just be wasting my (extremely limited) money because I'm impatient"? I'd *really* welcome any advice!
The GP surgery has no intention of measuring my B12 levels again at any point "Because we know the injections work". So taking supplements now wouldn't skew any treatment I might receive in the future - I've been told I'm on injections for life, though haven't been tested for PA, which has left me a little confused. Oh, and I have no idea about my folate levels, which I understand need to be decent in order for the B12 to work properly. I'm going to ask to have it tested when I go back for my thyroid test in another two and a half weeks, though I have no idea how well that request will be received. In the meantime I'm taking a B-complex that includes folic acid.
Again, thank you so much for any help anyone is able to give.
