I've had it for years...I take ropinirole about 7 pm. It sometimes drives me absolutely crazy, and the only way to get rid of it is to stand and walk.
When I forget to take the pill on time, and I wait a couple of hours, I'm sometimes up until 1 am dealing with it. DH says I do it in my sleep too.

It's one of the most annoying symptoms of MS. The drug is actually for Parkinson's patients, but they give it to MSers so we don't jump off a cliff

Call your neuro to see if you can get a sample to see if it works for you...
