Hi FriedBrain,

My advice to you is to see an Epileptologist (Dr. specializing in epilepsy) You can find these Drs. at an Epilepsy Center which are usually at University Hospitals or very big hospitals like Cleveland Clinic for example.
I do know that sometimes people who have MS will end up getting epilepsy I have an aunt who had MS and her neurologist put her on tegretol to help her with both the pain she was having and to stop any possible seizures she might have.
These nocturnal seizures you are having could all be related to a sleep disorder you may have. You need to go into the hospital and have a video e.e.g done along with a sleep study. Often people who have sleep apnea will have nocturnal seizures along with a rapid heartbeat and shortness of breath. If the Dr. does a sleep study on you along with a video e.e.g. they will be able to tell if this is the problem.
Some of this could all be do to hormones changing also. I know when I went through my change the seizures increased like crazy. Try taking vitamin B12 1000 mcg. a day to see if this helps also cut back on the carbs and starch foods along with anything with aspartame (nutra sweet) in it.
I was in a medical study this past spring where I had to take my temprature 4 times a day at the same time along with each time I had a seizure. I was also told to keep track of how many times I would yawn each day and write all this info. down. Then when I got a warning I was going to have a seizure I was to put a cool washcloth on my face and the back of my neck. Each time I did this it stopped the seizures. The study was done on people who have MS and epilepsy and they found that yawning helps cool the brain down so the less a person yawns the more chances they had of having seizures. I noticed the my temperature was higher each day that I had any seizures, and how when I put a cool washcloth on my face and neck it helped calm the neurons down and then I didn't have any seizures. Give it a try if you want to but the best advice I can give you is to get a sleep study done to see if you have a sleep disorder that's causing these seizures. I wish you the best of luck and May God Bless You!
