I used to get it a few times a week. Now it's down to about 3 times in 10 years. In case this helps anyone, here is what I do:

• I never sleep on my back anymore, only on my side
• If I do roll on my back and if it does trigger it, I focus on moving my feet and toes, up and down and this will wake me up within a minute or less.
• I informed the person sleeping next to me that if I become agitated or if I start moaning, they can wake me up simply by calling my name and saying "wake up, it's only a bad dream" a few times. I will wake up, feel thankful and peacefully go back to sleep, feeling safe and secure. Knowing that, the other person does the same.

A thousand thanks to the anonymous writer who shared this information years ago.
