Thanks, Ellie (and others...I'm lost again).
They occur with no prior warning or any triggers that I'm aware of.
I've been on Dilantin (300 mg before bed) since last Wednesday. I'm now supposed to go back in for a followup blood check...to see if my liver is still working.
I'm not sure of the brain lobe location(s), but will ask the the Dr.
I believe the blank memory wakeups have been happening for about 2 years, but looking though my records, and noticing what I don't remember doing or writing, it's been going on for much longer than that. Unless of course the seizures have been taking way bigger chunks (longer time periods) of memory than I'm aware of.
What's amazing to me is that there aren't thousands of others with the same symptoms. I'ts got the Drs. stumped; here maybe one of the true values of the Internet.
