Has anyone experienced these?

I work in NYC. On Tuesday I was on the subway en route to work. I looked up at the sign and it said the train was approaching a stop that is 2 stops ahead of mine.  The next thing I know, I am 3 stops past my stop with no recollection of the 10+ minutes that had passed from the time I looked up at the sign and where I was at that moment.  I blacked out.  The doctors are pretty sure it was a seizure. 

I was taken off Keppra (which was prescribed right after surgery) in early May.  I am now back on it, but I am terrified.  I do not feel safe leaving the house out of fear that I could be crossing the street and black out again.  I am lucky I was already sitting down and recovered pretty quickly, but...this is just scary.  I think I am more terrified now than I was before the surgery.

Any insight or encouraging words would be helpful. Thanks.

I'm sorry to hear that Amy. I also still have migraines which I know is normal, but the I never had any blackouts pre-surgery.
