Ataxia / tremor - herbal treatments?

My ataxia is probably the symptom of my MS which causes me most distress, annoyance, problems… It can be particularly bothersome when trying to eat… Generally I find it better when I am feeling relaxed and peaceful, having a shower sometimes helps. It is worst when I am stressed or uptight, tired or have a migraine.
The neurologist tried giving me propananol but this made absolutely no difference at all for me. I was given the very lowest possible dose, I took one tablet and about 20 minutes later I felt that my breathing was affected. Also when I had a nap later in the afternoon I woke up aware that I was talking to myself in my sleep. I won’t be trying that medicine again!
Does anyone have any recommendation for a herbal treatment that may help?
