Jappy, I'm glad to see you posting, but sorry about your lousy news.
I'm on LDN too. My neuro wouldn't discuss it, either, so I got a Rx from my GP. It takes awhile for your body to get used to it, but just a couple of months or so before you can build up to 4.5 mg. daily (optimal for MS).
It has given me more stamina. Not every day, but I have more good days than I ever used to. (I've been on it since last August).
Remember it's Your body, Your disease, Your decision.
Good luck on your remodeling, too!
