Yeah, that's pretty much what I'm referring to; not so much tremors or twitching. Seroquel started with the restless legs and the more I took medication like that, it progressed to arms, too, and then my neck and back. Couldn't stay still for anything. Also, it started just at night at around bedtime but eventually got to where it was happening all day long. Weird, though. I have been online looking for possible causes of this and I can't find anything. My doc doesn't know, either. The way he was talking, he had never heard of it.
