Hi Luanne,
Welcome to the forum. I'm sorry that you have a brain tumor this could be what's triggering the sz. My advice to you is to tighten up your muscles and fists the moment you start to sense a sz starting and this could stop the sz. I've been doing this since the 1970's and it has stopped many sz.
Another thing you might want to ask your Dr. about is the medical marijuana it is used for epilepsy, cancer, parkinsons, dementia and other medical problems the THC level that makes a person get high is very low while the EBD level is very high and it's the EBD that helps stop sz. and all of the medical problems I mentioned. You can get this in a pill form just have your Dr. order it for you and give it a try. Here's wishing you the best of luck and May God Bless You!
