I have it, and I've posted before I have a kind of crazy sounding method that so far has stopped the attacks, and that is drinking cold water. I don't know if the cold shocks the nerves and muscles, or what, but that stops it. Sometimes it takes a few minutes, but the time it doesn't stop, I'll go to the er to see if it's a heart attack, which it mimics. So far in three years, no er trips, at least not for that.
