Hi Hazzell,
Welcome! That is a hard question. I know it works for MS people, in many ways, but you don't have MS but a brain injury from the past.
I don't think any of us knows if it will help you. It might with energy, some pain relief, elevate your mood with higher Endorphins in the body. I am thinking it can't really hurt you in such small doses we take, so it probably won't hurt you to try it.
Never use the slow release form.
Have you read the LDN website? It may have more info there. Nice to meet you and good luck to you.
