Thanks for the link @strongtogether, I will look into those.
I was recommended Vitamin B12 by my psychologist of all people (Thompsons sub lingual) from Chemist Warehouse.
I have noticed a big improvement in the PN in my hands since I have been taking them, coincidence? who knows but I like the taste and I feel better mentally.
I also take Vit D, as I am low in that.
My feet are actually improving after 7 months, lol @Afraser "at the speed of a glacier" but I actually have some feeling in a few toes, even the ones that have been numb since 2016 (back injury). It is good to feel something, even the weird sensations are a welcome change ;)
