I took it and I found that I was feeling drowsy then neurologist changed it to Lamotrigine but no change in drowsiness after 4 months. It is affecting my lifestyle.
Don't know what to do. Like you I don't think I had Seizure but I passed out, my wife says I was fighting while going to hospital, there they found nothing with CT scan and MRI. I had appointment with neurologist today but I cancelled it did to COVID-19.
Good luck.
