Hi Jenny,
Welcome to the forum. I've had epilepsy for 35 yrs. and what you are describing sounds very much like a partial seizure known as an aura seizure, sometimes an aura seizure can lead into a complex partial or absence seizure with me. I've learned that the moment I start to see colors in my eyes and get a funny feeling in my stomach to tighten up all the muscles in my body and make my hands into tight fists, by doing this it stops the seizure. My neuro taught me about it yrs. ago.
I've tried 14 different AED's and not a single AED has stopped my seizures, I later found out that I was drug resistant so I started taking vitamin B12 once a day, and I started the ketogenic diet which is a diet high in fat but low in carbs. and protein. This has been the biggest help reducing my seizures even after having 2 brain surgeries. Also stay away from nutra sweet (ex. diet soda) I found out that if I eat or drink anything with nutra sweet in it it will cause more electrical activity in the brain and lead to seizures for me.
If you haven't started keeping a journal of all of your possible seizures. Get a calendar and write down what time they happen along with a description of the seizure. Also write down when you start and stop your monthly cycle. By doing this you may be able to see a pattern as to what time of day or night and what days of the month you are more likely to have any seizures. It's been proven that when the hormones change each month many women have more seizures. Also lack of sleep and to much stress and bright lights can trigger seizures.
