seizures
"Seizure free for over 2 years on Glenmark's Zonisamide. It would be closer to 5 years but the pharmacy switched to another supplier and I had 2 seizures and ended up in the hospital. 

  I do at times have some brief dizziness and notice that I don't sweat as much but these are light side effects given some of the brain numbing comatose side effects of other drugs that I have tried."
