I had a few good perks right away , too. The first day, I could stand right up without holding on and my balance was much better. Before LDN, I couldn't close my eyes without falling over....after LDN, I could, without losing my balance.
I was already SPMS, so it didn't go back and wipe out the permanent nerve damage, already done, but I think, it sure did keep me from getting worse.
Like Martha would say.."It's A Good Thing"
Worth a try for anyone IMHO!!
