Marc, I think you mentioned using polarity screens somewhere.  I find them to be somewhat helpful when I am in the middle of an attack, as in in pain, shaking etc at night.  I use the ones I got from Da Free John's group  http://www.dawnhorsepress.com/ProductDetail.aspx?PID=3292

This is not a recommendation of Da Free John btw.
