I have and occasionally still get it. There's not much can be done really. Once I knew what it was and read up a bit about it, then it got to the point where I was able to repeat a mantra in my head which essentially just reminded me that it was just a moment in time and it would pass so they don't really scare me any more after the initial split second 'I can't move' thing. But I don't suppose this approach works for everyone. One of the weirder aspects of it is when I think I am up doing my normal routine and part of me is screaming 'you're not brushing your teeth, you're lying in your bed!'
I guess just look at your life, if there's stresses and such things that can be reduced then probably best to get them under control and that'll likely have an impact. I don't think I've had an episode for the best part of a year now...
