weird sleep and epilepsy

I'm new to all this so sorry if I'm retreading something that's already been discussed. In addition to having what seem like complex partial seziures when I'm awake, I've been having a related problem in the mornings. Some mornings nothing will wake me up short of a loud noise (louder than an alarm clock) or physically shaking me. Some mornings I _seem_ to wake up but eventually, even as much as an hour and a half later, I fall back asleep. Afterwards I don't remember anything that goes on during the between-sleep periods. For example, this morning I woke up, finally, during a loud thunderstorm. After that I remember eating breakfast, but I don't remember how I got to work. I remember needing to call my health insurance company at work, but I am not sure this conversation ever took place. I remember lying on the couch at work (it's a small, cozy place and they have things like couches) and then nothing until a half-hour later, when I sat up. This sleep stuff, needless to say, is really freaking me out. Is it seizure-related? Has anyone experienced this? I can't seem to find any info on this event, and I get normal, full nights of sleep. Any ideas? Nicholas
