I cannot tell you whether or not my eyes roll back and forth during an episode of SP, but I do know that as I struggle to peel open my eyes during an episode I can feel my eyes flutter, but not neccessarily roll back and forth. I have never experienced a headache after an episode, but that doesn't mean that it's not possible. However, one thing is for certain, and many others who experience SP all say that after pulling themselves out of one, they find themselves falling right back in. This is especially true for myself. I cannot tell you how many times I struggled to pull myself out and as I start to fall back to sleep I go right back into it. This is the most frustrating and scary thing, because it makes me fearful to go to sleep and I get to the point where I am so sleepy, I end up nodding off and will experience several episodes a night, as many as 5,6, or 7 and sometimes throughout the entire night. It is something I cannot control and fight with it quite often, however, doctors don't really have a "cure". They know "how" it happens, but apparently, they don't know "why" and that's what I would like to know.
