My TLE was diagnosed about ten years after onset of symptoms, which were 'treated' as behaivoral, until I met an MD who develped the hypothesis that the brain might play a role in behaivor. I had neurosurgery twenty years previous to onset of symptoms. Answers to your questions.
Yes, it is well controlled with Lamictal, and in later years, Lamictal with Keppra.
No. I was in graduate school and my mind was in sixth gear from 4am to 10pm.
I have not heard of anyone developing a split personality, but I did have behavoral problems following onset olf symptoms.
It looks and feels like nothing. I look low and to the left and space out, returning to awareness after 30 sec. to 3 min., which is an eternity when I am not responding to verbal or visual responses from the person I was talking to. I just space out, then become aware, am initially confused and have no recollection of the topic or subject of the conversation.
I'd like to add that I have periods of confusion, sometimes in public, which causes problems. When a man missing a leg, the public doesn't expect him to run. If he's missing a right hand, they dont' expect to shake hands normally. But, when a disability is hidden by the seven bones of the skull, when one person sees you, they think you are just like them and make sarcastic remarks/actions when I'm confused.
