I'm sorry to hear that you're having a reaction to your pharmaceutical. Have you had an opportunity to talk with your neurologist about it yet? If not, I would definitely reach out to discuss different options.
I also wanted to share a video that Holly created. She provides great resources to our community there. She may also chime in to this post here, but in the meantime, here's a video to check out.
