:( soooo not what I wanted to hear.
I am out of choices for drugs to fight this stuff, and it's killing me. :*( Did you decrease the dose at all before you quit taking it? What are you doing now? Did the spasticity ever subside? Because I had it before, it is just FAR WORSE now.
I'm sorry this isn't what you wanted to hear. I'm sure there are others that would give you a different response, but this was my experience.
I took 4mg nightly for a year before stopping. After that, I tried several times to start at 1mg/night and slowly work up, but was never successful at getting above 2mg/night. In my case, spasticity was most troublesome in my bladder and urethra. I finally reached the conclusion that LDN was not a good fit for me.
I've used copaxone for about 15 years now. The typical problems you hear from people about injection site reactions have never been a problem for me.
Before copaxone, I had tried using betaseron and rebif, but I wasn't happy with the interferon side-effects, so stopped.
Everyone is different, and there are positive and negative anecdotal reports about everything under the sun, including bee-sting therapy, snake venom treatment, CCSVI liberation, prokarin, LDN, dietary modification, antibiotics, the list goes on and on. I think the trick is to keep an open mind, try various things, and find what works best for you. What works best for you may not work for everyone (and vice versa).
P.S. And, of course, it's important to keep your treating neurologist in the loop.
