I'm on the max of zanaflex. Doc told me to take it with food to avoid the possible fatigue, and I do. That is the only med that would make me fatigued. I have energy nowadays (when that spell of fatigue that lasts for days hits, it's another story

).
My DD took a pic of me sleeping during a dinner out one evening. I just plain bent over and fell asleep. She posted it on FB, the brat...another time DH said, "Get your hand out of your dinner." I'd fallen asleep and my hand fell into the pasta. That's how fast it occurs...
The jerking is new for me. It could be lack of oxygen, but it happens when I'm awake now, and I'm not gasping for air...
Just another fun thing to add to the list I guess...
