Length of Auras

Hi, I'm new here and haven't been formally diagnosed yet (I'm having a video EEG on the 26th) but some of what I've experienced make me question what's going on. My specific question is: how long do your auras last? Because so far I've had only partial complex seizures (the docs think) but before each one I had an aura that lasted anywhere from five minutes to forty-five. I feel exhausted for no reason, get dizzy, and feel disconnected. This is worse (for me at least) than the seizure, which happens either with one big jerk and then it's over or else unconciousness (and nobody has been around for one of those to tell me what I do). But from what I've read, auras traditionally last only seconds or minutes. Any thoughts on this would be great. Thanks, Nicholas
