Nocturnal Seizures / Night seizures

I had my first gran mal April 2007.  Since I've kept notes by dates, doctor visits, blood test numbers, various tests I've gone through, how my body feels with diet changes, excercise habits and medication changes.   I've had multiple EEG's and MRI's and they all have been NORMAL.  I'm sure you've read that there are a variety of reasons a person can have seizures.  In short, I've learned that my thyroid (TSH #) was 9 in Dec. 2007.  Normal range is 0.465-4.68.  I was hypo which meant I was tired among other ways it affects my body.  Now my TSH is around 3 and it seems to my personal number for feeling good.  I've learned that if I eat high glucose(sugar) food for example, a bowl of ice cream around supper time and don't eat a high grain sandwich before bedtime I will have dreams, wake up startled, have a feeling to urinate, sweat sometimes, with a choking feeling like I was going to throw up that in the past has lead to uncontrollable shaking of my right hand and body, before passing out into a gran mal.  This event has happened to me in Sept. 2007 and Jan. 2008.  Scary, yes. I've gone from 750 mg x 2 daily generic (Keppra) to 250 mg x 2 daily with my neurologist's guidance.  I work with my endocrinologist in getting my thyroid medication level right.  I work with my GP to keep him up to date and his guidance on blood glucose levels, blood pressure, weight gain, and cholesterol.  I do my best to watch what I eat, don't over excercise (over 2 hours), and always eat a high grain sandwich with protein.  I avoid pop and juices.  I drink water, tea and milk as much as possible.
