Is LDN really a useful drug for MS?

[Guest guest]

I have taken LDN for a year-and-a-half now (at $45.00 for 30 pills),

but now I am questioning its usefulness. At the beginning, it seemed

to help my walking a great deal, but now I really have to focus on my

walking to avoid a fall. I still refuse to use a cane. I have had MS

since 1977 and I can still walk (though unsteadily), talk, write, type,

drive and many other activities. I exercise every day - pool exercises

and a 'Sit and Be Fit' exercise group. Am I expecting too much - like

going back to 1977 and not getting MS?
