I'm sorry to hear that patticake66. It is used for cancer and many other diseases/disorders besides MS.
When I have to stop taking it, for either surgery with anesthesia, or even for conscious sedation, I find I have to try to start it up again ASAP. It is harder getting back on it. It really elevates my mood, and helps with any odd pains I get, a blessing. I have used LDN for about 3 years. I get it compounded with sucrose, since I can't tolerate other fillers.
I tried some of the other DMD's, but LDN helped me the most. Also having the CCSVI procedure has helped me too. I was the biggest LDN naysayer for years. I thought only what my Neuro said was true about DMD's. Now she is a believer in LDN and CCSVI and so am I.
We can't help everyone or please everyone, but we do try.

Where there is a will, there is a way. "HOPE"
