Be careful with Zonisamide, you will start having more seizures at night because the deep sleep is not happening. They have done studies on us now and the studies confirm this. When I came off mine post-surgery, I had to go back to the dreams I would have had post-high school and catch up on every dream I should have had. This took over a year to quit the crazy dreaming. I am now more then ten years post-surgery and seizure free.

Another dry mouth. I Always have a bottle of water with me at home
or out..

Not sure which medication can cause dry mouth but I have it also. Another thing is that if I am out in the Heat I often sweat 😥 profusely. It is why I almost always have a drink with me. I even have noticed it sometimes when I doing some daily housework

I was told to use Biotene Toothpast and Mouth Rinse. Other brands make dry mouth products. I also suck on ACT Dry Mouth Lozenges. The medication I take for my Nervous Bladder gives me Dry Mouth. I also need to drink a good deal of water. A side effect of Epidiolex is very loose bowels.

Yes to the dry mouth
