I've noticed a coorelation between stretching and yawning with my seizures. In particular, I do these compulsive strings of half yawns (meaning, they're full yawns, but for the most part I'm not sucking in air, just stretching my mouth or some such) and these extended stretches. I'm not sure if they're part of my "episodes," an aura to them, or part of the post-ictal, but I've definitely noticed they're there.
Does anyone else have/do something similar? I'd love to hear. :-)
