Good luck with your treatment, it seems to work differently for different folks, but that seems to be the norm with MS.
I am currently on day 5 of my fourth attempt, using different dosages, and am determined to see it through this time.
Last night I went to sleep the moment my head hit the pillow - I was up an hour later for a pee, then slept through until morning. Without LDN, I am up and down a minimum of five times in a night. If nothing else improves, that alone will make the whole thing worthwhile for me.
All the best,
