t know if this same answer will fit, but I wanted to share in case this information could possibly help someone else who is experiencing this paralysis. Apparently, I have
narcolepsy (with cataplexy); by taking a very detailed
history all the way back into my early childhood, they were able to determine that I had the narcolepsy BEFORE I had POTS, but the cataplexy only showed up when I started having syncope.
