Hi Batik,
I'm hoping that you were able to get some sleep and are feeling a little less anxious. I wonder if the jerking movements are related to one of the medications you were taking.
I have RLS and I actually don't get any jerking movements with mine but some people do.
Please let us know how you're doing.
We used to have a lot of Info. posts here on RLS and other things but I can't for the life of me find them this second.
