I just wanted to share a story with you.
I met an online friend at a LDN support site years ago and we have been e-mailing, off and on, since.. He was one of those gun-ho advocates of LDN..

To him, it was a miracle drug. I was on LDN, too but I sure didn't share his enthusiasm, since I was not having as much symtom relief as he was.
Just recently I wrote to ask how he's doing and after about 2 weeks, he wrote back to tell me that he had been in remission for the last six years, on LDN.....but......He started having more weakness in his limbs and went to his Neuro.
Many tests later, he was told that it wasn't MS but ALS..

His Doc said that it's amazing that, it hasn't progressed any further than it has and to continue to take his LDN. His Neuro is convinced that it helped to hold back the progression of ALS..
He is still on LDN and doing pretty well so far. I will keep in touch to see how he does in the future. I hope and pray, every day, for him, that the LDN continues to hold off the ALS progression.
