Kay,

Have you every hear of weighted blankets?
They are marketed to autistic children who suffer from sensory overloads.

They work for some people with bipolar as well.
Searching Google Scholar I found that Heated Blankets can
help as well and they are much cheaper.

This can calm some people:
Soaking feet in Epsom salts -- magnesium can relax.
