Oh my, it sounds like you have gone through a rough time. Did they happen to suggest seizures and the memory loss being due to hitting your head during the seizure? I've had a few episodes where I lost track of time (forgetting how I got home, things like that) but nothing to that extreme as you have mentioned.

As you said above, what they found on the MRI could be what's triggering seizures and the other problems. I would highly recommend getting the VEEG mainly so they can monitor you while you sleep since you appear to be having some form of nocturnal seizure (or an event that's similar). Even if it's just a 24 hour study, it should be enough to get a good solid read while you're sleeping.

Make sure to keep us updated, I'm very curious to see what the formal diagnosis is. And even if it's not Epilepsy, this forum isn't just for Epilepsy - so make sure you stick around.

PS: Thanks for the compliment, all of that stuff on my head didn't make me feel very pretty. Hehe.
