Niacinamide for years now to control nerve pain. I've not had to go to meds yet as this works for me.

Interesting that nicotinamide is related to what I've been taking.

As the B vitamins are water soluble you won't overdose.

When nerve pain flares up I take 3 500mg caps in the morning and then start dropping down as pain subsides.

Don't forget to always take B vits on a full stomach or you will get sick.

Hope this helps and your post has given me insentive to keep taking this.
