I used a Chi machine for awhile before I took meds andf found it helpful in relaxing me inititally. I would fall asleep!. Then later it served to override the tremor and mitigate the pain/discomfort. It enabled me to talk on the phone! I ended up giving it to a friend w/ RLS.

I doubt that the benefits claimed are true ( spinal adjustment, exercise) but it did give me some relief. In fact, I may get another one one of these days.
