Welcome, I wish you were writing under more pleasant circumstances.
I went through several months of seizures that were attributed to MS. I can well empathize with your wife and I must honor you for your devotional support. For me, bed rest was my best medicine. I spent nearly 6 months on bed rest to fully recover. I also found that if I was lying down, the seizures were not as intense (or so it felt).
I have long since cycled out of my seizures and I have not had one in over two years (I think). My service dog was the first to notice something wrong and alerted my family. He has not alerted for a long time, so I feel safe.
I will keep your wife in my prayers. MS can cause seizures. You may need to change your neurologist if you suspect MS or you are not getting satisfactory answers for which you seek.
