Is it just me?

I just started having these "episodes" over a month. I'm a little scared as I havent seen the neurologist yet.  I dont remember what happens during these "episodes" but my sister tells me I look as if im drunk and can only reply yes/no/ok. this usually lasts 10-20 minutes before I fit and convulse. I then come out of the siezure ok but still disorientated and confused. In all this last 30 minutes and I have no recollection afterwards.

Any advice out there would be a huge help.
