Boy, it's comforting to hear I'm not the only one.

I've had this on two occasions, each lasted a few days. It made it impossible to sleep, and every time I'd start to drift off, another "Firework" would light up and make me wake up in a panic.

I have no idea if this was anxiety (the first time it happened I was going through a lot of stuff), MS, a combo, or something else completely. I never told my doctor. All I know is that it always scares the heck out of me.
