I've had times like that (especially while trying to sleep), and listening to guided meditations help me. I also often will drink a glass of milk and take a Xanax or a little extra Risperdal (pdoc told me I could). If it doesn't go away, I would talk with my pdoc if I were you. You may also want to write down how often this is happening and try to see what is triggering it. Are you having too much caffeine?

I'm sorry you're having it so rough.
